Yep, I have seen the ads in old gun magazines, and it looks like they imported boat loads of them. I guess it was all over the place back then, kinda like the cheap (well...) Russian captured stuff we see nowadays.
I will definitely not try and shoot the Tokarev round through it, the recoil in a TT-33 is quite respectable and I don't even want to think about what it would do to the old Broomhandle... or what it will do to my hand, holding that tiny Bolo grip...
So what's the verdict on this one? Restore it and make it a good looking shooter, or keep it as is hoping that it will one day be appreciated as a collectible?
