I have been looking at a 1st gen Sheriff's model on GI, shipped to Houston Texas in 1896. The serial number does not appear on the lists that have been previously posted here of known Sheriff models, but I suspect the lists are not 100% complete. In the GI listing there is a pic of the Colt letter, but of course with revolvers in this price range fake letters do occur. I would be interested in any thoughts on this particular revolver - for me the GI search function does not find it if you put in Sheriff's Model, but it does find it if you put in Dunlay Hardware. Thanks in advance for any thoughts.
