Phantom Captain,
I was in BP back in the late Sixties in Indiana and did Friendship quite a few times. Had A lodge on the primitive range with the 64th Virginia Volunteers, the bad boys with the bugle.
I might have known your dad. Knew Capt. Max Vickery President of the NMLRA at the time, personally as he was one of my Mentors, along with Art Holly. I built 19 rifles and 5 Hawken Pups.
You can PM me if you prefer.
