"To Chief of the 8th Department, Military Engineer 1st Class comrade Afonin
November 18th, 1939
Summary
- A-34 vehicle (as of November 16th, 1939):
- Blueprints for 31 groups have been sent to the plant.
- Blueprints for 3 groups have not been sent to the plant completely.
- Blueprints for 4 groups are not yet ready: the driver's seat, the radio equipment, the turning mechanism, the instruments.
- 307 parts have been produced out of 1229.
- Parts for convertible drive trials on the A-20 will be ready no sooner than December 1st, 1939. Delays are caused by plant #500 being overloaded with orders for other tanks (A-7, D-3, D-5).
- Trials of the A-32 (loaded to the weight of an A-34) are complete. The tank drove for 1230 km, including 200 km on the highway. Mechanisms functioned in a satisfactory manner during the tests. During trials on the highway the drive sprockets wear heavily. Special trials (grades and slopes) are still to be performed on the A-32.

Is there a list somewhere with all of the development/industrial designations (A-7, D-3, D-5)? I don't know what those three are (BT-7, KV-1, and KV-2???).
ReplyDelete"A" is the factory #183 code, so the A-7 is the BT-7, A-34 is the T-34 prototype, etc.
DeleteI don't know what D-3 and D-5 are. D is usually the letter code for factory #9 guns (D-25, D-5, D-10, etc).
