What air gun is this?  No ID markings anywhere on the metal.

I'm not sure, but I have a Chinese B3 with an identical looking stock. But mine is an underlever cocking gun

Its one of the B1s....B1-1/B1-2/B1-3

I have 2 of those! Made in shanghai china but no other marking on mine either. I also have 2 inder levers made at the same place, they all have the same markings. The under lever Ive been told are B-3's so the break barrels I assume are B-? I have a 22 and a 177. 22 is at my parents in Fla they found it when they moved not too long ago. Good little shooters for the money. My 177 shoots in the 600's.
