That's a very nice Norev model made in plastic. they were very well made and quite accurate. They can suffer from a kind of plastic fatigue where the plastic shrinks and they go out of shape , you can stop this from happening by painting it , no good trying to fix it by painting it later. I don't have the B20 but I have a few Norev models and they all have a very good likeness to the real thing.
Thanks. David.
