My first flintlock was a Freddie Harrison rifle. I bought it at DGW 4/16/74 on my way home after being discharged from the service in Louisiana.
It was one of his earlier efforts with a little too much wood left forward of the rear ramrod thimble. 13/16 .45 Douglas barrel and a lock Dixie sold in kit form at the time as a Southern Mountain Rifle lock.
The lock always gave trouble and was eventually replaced with a small Siler that was almost a drop in.
