Stainless 1860 Army
This is belated, but congratulations on your find. I have not been to the forums for many months so I missed this posting earlier. Ken, this is the ONLY Uberti full fluted cylinder Stainless 1860 Army that I have even seen a picture of. Wolf sent me pictures of the Centaure Full Fluted Stainless 1860 Army but even these are extremely rare. Yours is a 'One of a kind' find. If I had seen this on an auction I would have gone $500+ bidding.
A real find. I would bet money that the messed up grips are from a shoulder stock that evidently was used often with this revolver.
