The production of tank hulls, armor plates, tank turrets, shields, guns,oilers for railroad locomotives and tubes was reported for the time of observation (see production). Production was resumed in the Summer of-1946 and about 40 percent of the pleat was in operation in December 1947. Full-scale production was not reached early in 1949, workshop bu i igi s 8 and 88 still being under construction. plant installations: (the number enumeratlons o e about sketch- of the plant installations is based a -11 sources.

(b) Production: The material to be smelted is conveyed by an electric szs- pension railway from the storage dump to the furnace top. (One source said the material-'is transported by cranes into the furnace). The base of the furnace is a square fireplace where the liquid,. iron is collected and tapped. The molten iron is conveyed in ladles by the suspension railway to the casting molds or to the six casting machines. Eighty tons of scrap or 40 tons of iron are processed in one smelting. The scrap smelting process lasts 24 hours, the pig iron smelting process 12 hours for each furnace. The ingots used Approved For Release 2006/05/25 : CIA-RDP82-00457R010100130004-5 0i--j.

Kind of production (1) Tanks. Tanks were repaired towards the end of the war and it was explicitly stated that complete tanks were no longer manufactured after November 1945. It was reported however that covered tanks were shipped out of the plant during the night. Tank coverings (*Panzerverschalungenwj without suspen- sions, tracks and engines, tanks without bogie wheels, guns, tank hulls and superstructures and technical installations were also reported. The tank hulls are allegedly shipped to the iuirov plant in Leningrad for final assembly. The sources supplied the following confused and hardly usable information on the development of a new tank type in the Izhora Plant: The wooden model of a new tank type was mentioned in the Spring of 1946. A test model of the new tank type was manufactured in the Fall of 1946. The production of a very small tank type was mentioned again in February 1947. The tank was apparently completed in April 1948. A new tank type (flatter in design tha the T34) was again mentioned early in 1949. Production started %arly in 1949.
