Lyman Plains Pistol vs. Pedersoli Kentucky Pistol?

[EljaySL]

Now that I've thought about it a bit - I can give you at least one historical example of somebody using a single shot percussion pistol as late as April 14th, 1865.

And that even though they had various pocket revolvers by then.

I have a Dutch naval percussion pistol dated 1845 on the cartouche stamp so they were being made and used during that period. It has a bore of about .700" and the nipple is sized for what we now call a musket cap.

Does anyone if the locks on the Lyman GPP and GO rifle interchange or is the pistol lock smaller?
