No - it's a Tula MC-11, This was their top-of-the-line shotgun, made on a Beesley action.
Tula made a handful of these shotguns, and I've seen at least 3 others on the market. The Soviet government used a couple of them as presentation guns to important diplomats.
Here's one that was at Julia's in 2009:

I've handled and inspected one. I think my friend still owns it. It was beautifully made, but not quite a Purdey. I was more of Tula's interpretation of a Purdey.
Fantastic gun, though.
