Yes this is one of those with the "Made in Japan" barrel. I bought it at a pawn shop just off of Ft Bragg in 1987 for $70. I gave it to my son this weekend and we went to shoot it, but the flint was bad, so I replaced it with a spare I had for the 40 cal I bought from Ken Guy. The flint is a bit big and the hammer can't go to half cock. I removed the Made in Japan from the barrel a few hours after I got it home back in '87! I couldn't hardly stomach having a "Jap" rifle in the house that wasn't captured by a GI!! So, after changing the flint yesterday, the rifle shot every time! It was a misty, damp day and we were shooting by the Flint River here in Northern Alabama. It was dead on- we were hitting cans from 50 - 60 feet consistently, and a pumpkin for further away! I also got a chance to shoot a newly acquired .32 cal I picked up in Barboursville, KY this weekend from Robert Kidd. It was like a cap gun compared to the old 50, but equally fast and accurate!
Back to the reason for the lock question- this lock is very fast and reliable. What size flints would some of you experienced fellers recommend?
Thanks,
Bill
