Thanks. Now that I know the model of the revolver I can properly evaluate Baldwin’s statement. I have the cap and ball version, which may have a similar hammer mechanism. I won’t know without a bit more research.

Here is a schematic of the two versions of the Colt that Pietta makes. One has a transfer bar and one does not.
