10 a. Eight Soviet committees from Rerlin-Karlshorst visited the
Neustadt/Orla (M 51/3 84) plant from 1 to 10 December 1949.
During the inspection they found that the mesh, except for a
small part, did not meet the technical specifications. The
wire weaving firms maintained that they could not manufacture
thinner mesh with the available reeds.
b. General Rudenko returned in the middle of December 1949
and again telephoned the Ministry in Mose= from Neustadt,
via the former Komendatura (now the Soviet Control Commission).
Moscow gave the following instructions by telephone:
1st quality mesh, maximum tolerance of shifted warp threads
90 microns (1/1,000 mm)
2nd quality mesh, maximum tolerance of shifted warp threads
120 microns
3rd quality mesh, maximum tolerance of shifted warp threads
over 120 microns
2. From then on mesh was inspected and accepted in continuous
sequence. Time pressure became so great that workmen could
Sleep only two hours during some nights.
The third quality mesh (a stock of some 100 meters) was
almost entirely rejected, ,as it had too many defects.
a. A Soviet official by the name of Pavilov, especially autho-
rized by the Ministry in HOSCOW and producing an appropriate
letter in Russian to that effect, came to accept the mesh.
According to his instructions, each ro1322of abouti50;to 60
meters of mesh was packed in especially light but strong boxes.
The gross weight was 20 to 25 kg.

3. a. The boxes were loaded on a Soviet Army truck which arrived
on 18 December 1949. According to Pavilov the shipment went
to Berlin and from there immediately by air to Moscow. Although
the Soviet representative promised another chock would not
be made for some time, additional mesh had to .be tested two
days later. These -stocks were actually part of the January
quota and were not supposed to be provided for acceptance
before January. Conversations of the Soviets -indicated that
they were eager to deliver, as much as possible bOsore the end
of the year.
b. About 1;400 meters abOVe the prescribed annual quota were
accepted. Part of the material even had to be cut off the
looms. The testt of.. the weavings had to be done with the
greatest possible accuracy. 'A record (in five copies) had to
be kept on each lot which might be UP to 1,000 meters. (Trans-
lations of two such records are annexed).
c. A special authorization, No 5/57, dated 12 'December 1949, of
the Reparations Administration of the Soviet Control Commission
was submitted during, acceptance as. all weavings did not corre,..
spond to the technidal specifications.
4. Negotiations have been' under way since 10 December 1949 to de-
termine the 1950 production schedule. The Soviet agencies-had
obviously not come to an agreement as to whether they should
ordpr the old. weaving type of 10,000 mesh or a new one of
22,000 mesh per square centimeter, 'According to a decision
made at the end of December 1949 all firms.are to produce an
improved twill weaving of 101000. mesh per square centimeter,
The tolerance of shifted warp threads may not exceed 90 microns.
This decision indicates that the reeds needed for these weavings
as well as the lamellate striwsteel which was to be delivered
already exist. Large stocks (about 8 tons) of the
required nickel wire are afbo stored in the Hettstedt (M 52/
D 64) Non-ferrous Metal Rolling Mill.
a.. The conversion to the production of a 22,000 mesh weaving,
which apparently was preferred; would have taken about six
months. This would mean that no. firm would have produced the
first weavings of this kind before May or June 1950.
5. NoOdetailed information is available on the required amount.
The Eilhauer Firm in Neustadt/Orla will have to deliver about
25;000 square meters of the improved 10,000 mesh twill weaving.
A similar weaving of 7,000 mesh will also be delivered (amount
still unknown).

Comment:
the Zonal Metal Weaving Plant in Neu-
stadt/Orla is also the control station for vire meshes manu-
factured in the Soviet Zone of Germany, which are. shipped to
the Soviet Union on reparations account. The annexed translations
$.
of test records Nop28 and 29 regarding reparations deliveries
of Raguhu and Graefenthal Wire Weaving Plants give a good
insight into the methods of testing.

2,. According to para.4,the wire meshes to be delivered to
the Soviet Union on reparations account in 1950 must be an
improved twill weaving of 10,000 mesh per square centimeter with
warp thread shifts not exceeding 90 microns. The wire diameter
must be 0.038 to 0.042 mm. the 50X1-HUNI
Soviets started to have wire weavings produced with 7,000 mesh
per square centimeter with stronger wire material (Wire dia-
meter 0.050 to 0.055 mm) with a view to filling the quota of
60,000 to 70,000 square meters of wire meshes required for 1950.
The managers of the German tire Weaving plants, referring to the
shortage of machinery and skilled workmen, declared they would
be unable to produce such an amount if they have to fulfil the
condition of manufacturing weavings with 10,000 mesh per
square centimeter and warp thread shifts not exceeding 90 microns.

Test record No 2, dated 29 December 1949, of the Tewa *Ire .50X1-HUM
weaving plant in Raguhn (M 52/E 15) regarding a lot of nickel
twill wire weavings (10,000 mesh per square centimeter) wire
diameter 0,038 to 0.042 mm totaling 863,51 square meters.
The lot consists of 18 rolls, 100 centimeters wide and 863.51
meters long, totaling 863.51 square meters.
Reparations order: F 52/917541
Trans No: 238 066.
The wire material used for the weavings was supplied by the
Hettstedt (M 52/D 64) Non-ferrous Metal Rolling Mill. The firm
submitted a certificate showing that the wire was manufactured
according to GOST 2179/43 with less than 0.15 percent manganese.
The weavings of this lot were tested in their entire length
and width on a special test table with light. installation and
optical instruments of special design. The firm measured the
wire diameter at two points in the woof with five threads each
and the wire diameter in the warp at five threads with a micro-
meter accurate to within two microns.T The difference between
the woof thread diameter and the warp thread diameter varies
within the tolerance of 0.005 mm and thus corresponds to the
changed conditions of 26 October 1949.
The maximum width of the weaving was measured and found to be
within the tolerance of 1,000 2 10 mm.
The statements of the Tewa firm regarding cracks in the weaving
correspond to those made in the waybill.
The weaving is not clean in some parts.

The number of defects found corresponds
to the statements made in the waybill. A compilation of the
discovered defects such as wire ruptures, knots, holes, woof
thread breaks, widened parts in the woof and warn thread shiftl
are listed in the annexed chart. 1 50X1-HUM
Soldered joints are also in the weaving, 50X1-HUM
According to tithe technical specifications, the weaving
has to be tested for shisted threads. This is impossible because
the Tewa firm has no optical instruments for this. 50X1-HUM
The warp thread shifts ,representing the mesh width exceeding
the tolerancerwere searched out with a magnifying glass by
following a lino in the entire width and were measured with the
ocular micrometer.
To have a survey on shifted threads in the woof the Tewa firm
investigated with a magnifying glass (sixfold enlargement) on
three different lines at two lateral parts and in the center part

of a one-meter long section. Ocular micrometer measurements
were made on some points of these lines, For the time being
it is impossible to mnke a thorough investigation for shifted
threads In the woof with the available optical instruments
(magnifying. glass and ocular micrometer). These defects can'be
accurately oetermined only with a projection instrument
which the Tern firm does not possess.
During the test for shifted threads in the woof it was.found
in all rolls that there were constantly irregular. spots of
.about 0.5 to 1.5 centimeter length which could not be determined
numerically. On these spots the meshes show a plus or minus
tolerance. Most of the irregular spots have a t:toierance of.
77 to 80 microns. There are also some spots which are below
the - tolerance,
The following defects were discovered in all rolls during the
woof test:
In the transition from one wire. shade to another (always occur-
ring arter..4 Isnot In floof thread) there are about 9 to 15
shifted threads causing shifts (tGasson") in the woof which are
below the minus tolerance (mesh width 25 - 35 microns). One square
meter of weaving averages 8 to 10 of such vire transitions.
More were also occasionally found.'
The number of meshes was tested at three different sppts. The
result was 27 meshes in 2.7 mm.
The representative of the recipient made random tests after
I
had finished inspection. He could convince himself of the >
accuracy of the waybill indications.
The weaving does not correspond to the technical specifications
according to the test result, In compliance with the.wish of the
recipient this lot is composed of rolls where shifts in the
weaving are not wider than 103 microns.
The boxes of this lot are marked with a diagonal stripe (4 boxes
red - 14 boxes green) at the front part as desired by the
recipient. '
The weavings were accepted on the basis of the authorization of
the Reparations Administration of the Soviet Control Commission
No.,. 5/57 dated 12 December 1949. As the weaving does not comply
with the technical specifications, the Reparations Administration
can make a discretionary price deduction.
In reality
the material looks better than shown in the waybill compilation.
