It could be right!
I had a 33-1 with a 2" barrel, original box and papers! Everyone, including me, said it should be a 32-1 as the 33-1 came with a 4" barrel only. When I lettered the gun it came back as a 33-1 shipped with a 2" barrel. Assembled wrong, using up available parts, frame stamped wrong, who knows but the factory did it!
