Leningrad SPGs

Remember the SPG on the T-26 chassis that showed up on the Leningrad Front? For the sake of convenience, it was referred to as SU-26, but it turns out that's not the real name at all, nor was it a wartime improvisation.

To the factory director

I ask you to order the Planning Department to begin preliminary development of the following:

1. SU-51: ZiS-4 gun on the T-50 chassis.
2. SU-52: AA SPG on the T-50 chassis.
3. T-26-6: SPG with a KT-28 gun on the T-26 chassis.
   This work is to be done on the orders of Marshall of the Soviet Union, comrade Kulik
4. T-26-8: AA SPG on the T-26 chassis.
   The project is open, but no work has been done."

Here are the SPGs being assembled.
