Bean is not a single maker but a family of gunbuilders that span 100 years of development.
William Bean entered TN in 1768-69 claiming the title of "first settler" in the state. He was a blacksmith and gunbuilder, but none of his work survives.
He fathered several boys that carried on the trade and spread the family through the state.
The family is given the honor of credit for development of the long slinder iron mounted southern mountain rifle.
Lolipop tangs, banana patchboxes deeply browned barrels and black lacquer finishes were dominant. Very diferent school from the PA rifles, sort of the assualt rifle of their time!
Some of the best photos available are in Foxfire 5 (that's the one that is always gone from the library collection). This issue of the foxfire series is a must have book for ML shooters. Do not worry about missing any details due to the B&W photos, the Bean guns are all B&W.
Wierd Jack, if you closely study photos of origional guns from all angles you will see in one glance the diferences between the Dixie gun and any gun that would have existed in PA before 1800.
There are more diference than just shape of the guard, shape of the lockplate etc. There are also diferences in thickness of the butt at the plate, wrist, lockpanels and forend. Diferent profile for swamping of the barrel. The archecture is totally seperate as a class of firearm, as much different as a jagger and a fowler.
Use of this gun for accurate reenactment purposes would be similar to taking an AK47 to a WWI reenactment. There is actually less time span between WWI and the AK than between the two design schools we are discussing.
It appears that there were two schools of design that sprang from the German tradition. The northern and southern german settlements swaped tradesmen frequently. In the south they blended with and absorbed from other cultures, in PA they remained more German in heritage.
The real kick is studying the development of the "poorboy" in the south and the "barn gun" in PA. It's like the two kids that went to different schools together!
The Dixie guns make pretty good shooters, they just are not "correct" for for the time you have stated.
