be Hearin; aorapasa (Induktions and Faders-Kompass)
Similar conditions to those in (a) above. The development and'production
will be conducted by Askaniao
c. kas- (Log)
Askania will develop logs with the electrical connections of the drive (sic)
supplied by the RFT. They will have a complete monopolyo.
Sounding eciuiprient
As'cania will produce the (Thomsen-Lot", and the R1!11 the 'Mehmeache Echo-
Lot" .
e, Pelorus or bearing compasses (Peilscheiben)
The development of those will be undertaken by Askania with the attached
telescopes, ote., supplied by the "Optischc ;der'_:e., Rathenow"o Magnifica-
tion will be increased in. the telescope from. 2.5 to 30 X. There will
be no other firms in competition,
f. Compass magnifiers (Kompass-Lupen)
For enlarging compass readings (steering). Production and development
by 'iskania and ithenow optical viori:ao
Clear view screcn4 (Klar. ,i,chtsc.ieiben)
These are fitted on the bridge of vessels to throw off spray or rain
(they consist of a rotating glass disc). The production will be carried-
out by Askania but the glass will be supplied by Schott (Jena).* See
paragraph 3a below.
ho Artificial horizon (Ktinstlicher Horizont-Kim-n-.lcsoar)
Development and production by the Hildebrandt firm of Freiberto
i. Heeling recorder (Kr?tngungsmesser)
Production and development by Schiffswerft, Stralsundl;in conjunction with
Askania.
sextants (Sextanten)
The devclo-'-lilt and production of the sextants will be conducted by the
Hildebrandt firm in i?'reibergq The principal difficulty encountered in
production is that of the reflecting mirror on the am of the sextant
reflecting direct rays from the sun. The mirrors will be supplied by
Schott (Jena). (3y means of a better melting process the glass, it
is hoped, will be free of fa.i.lts).
Position iiits (Positionslaternen)
To be prod-aced by various fires in the DDIt (nw^mea urt molnt). The main
criticism conccried the poor containers for the la.ips which hitherto
have not been water tight. In addition, the internal fittings Were
not properly secured, which, caused poor electrical contacts and shorts.
The screws and other fittings more poor and caused corrosion.

The development of this equipment will be conducted by Zeiss (Jena)
However, the Seepolizei representative reported that specifications
for vessels which were planned for the future for the Seepol.izei force
had not yet been definitely settled and consequently no plans for equip-
ment could be specified,
