Yep, it's a six incher. The best I can say about the date is between 1895 and 1901. The serial number was long gone back when my grandfather gave it to my dad, in the 1950s. It's either an 1895 or an 1896 model. It's got the RAC acceptance stamp on the left side, but the grips are wrong (I think that they're from a later police model).
I've shot it a few times with some really lightly loaded .38 Colt rounds, but the lockwork is getting a little cranky, so I've relegated it to the peg of honor.
Well we don't rent pigs and I figure it's better to say it right out front because a man that does like to rent pigs is... he's hard to stop - Gus McCrae
