A Russian collector supplied me with this tid-bit of info:

After the WWII a gun making school was established in Tula.

The 1st shotgun was called TS (TC-1). It was a copy of a Lebeau sporting weapon(as HD notes).

The 2nd was called TS-2 (TC-2) and was a copy of Purdey self-opener(assisted opener) and was made by TCKIB (-Sporting and Hunting Guns Central Research and Design Bureau, Tula).

It was weak as sporting shotgun . The MC-11 (MU-11) was made on the basis of TS-2 .

The difference is reinforced bar and longer flat. The MC-11 has two other top lever actions: Greener cross bolt or Purdey latch.

The shotgun: MC-11 (MU;-11); Modifications: MU11-1, MU11-2, MU11-3, MU11-4(note the Us are as close to the actual character)

Destination: sporting

Caliber: 12 Chamber: 70 mm

Barrel length: 750 mm (trap), 675 mm (skeet) ; Steel: 50A (low-carbon, Izhevsk prod. - this is the 4 Ringe that replaced Krupp's 3 Ringe post WWII in Germany) -
