Re: Old gun, loaded in the front. (sorry for the english, i am danish)
This is the Tower Flintlock I've described.
I've shot it with 40gr. Pyrodex; newspaper wading; 4Fg powder in the pan.
Big ffsBOOM; lotsa smoke; and a lot of cleanup.
WEAR shooters glasses!
This is a repro; I'm sure I can get $150-$200 for it; wouldn't sell it for less.
Picked it up at a local gun show about 10 years ago.
