Actually, you'd be surprised at what you find floating around up in our neck of the woods. But, no, it is not typical. Most trigers at this stage of the game were store bought as were the locks. A lot of smith's bought their barrels as blanks and rifled the barrel themselves. I know you don't have the books, but if you look carefully at some of the pictures of originals in the Ohio Longrifle Collectors series, you would see all sorts of triggers, some much more closely resembling those you would see in the southern states, but mostly the triggers are like those that Davis supplies.
