This is an Open Top Navy Revolver in .38 special, with a nickel finish. This is manufactured by Uberti and imported/sold by Taylor's & Co. Barrel length is 5.5 inches.

I bought this to accompany my 7.5 inch version but only took it to the range once so I'm selling it off. It is like new, with original box and papers.
