Right now Flintlocks Etc. has their Kentucky Big Bore (.50 & .54) on sale for $360. That's a Pedersoli made gun. Take a look at it on the Flintlocks Etc website.
A year and a half ago, when PA legalized flintlock pistols for deer, I wrote to Lyman and suggested they offer their pistol in flint. Never got so much as a form letter acknowledgement.
