The piece I currently have, (which is going back for exchange), says exactly:
"CAL. 44 BLACK POWDER ONLY - A. UBERTI ITALY
and that is found underneath the barrel.
Interestingly, if one types this "Uberti black powder disclaimer" into google, the top rank for that is this thread.
Mine is stainless steel, the target model, made in 2008. I find no Uberti Factory Stamp anywhere on the frame or the barrel.
I'm beginning to think that Uberti has at some point stopped putting it's Factory Stamp on certain models of it's pieces. And that's what this thread is about.
