Thank God You're Here My Friend...!! Not that I'm an expert...but I never even heard of that concept. I did know Val was John Moses Browning's Son...I have a few pics of him in uniform with a BAR.
Great shots, Shooter. And if you're talking about Short Recoil, I guarantee you've heard of it. Just about every pistol that's not blow back operated uses it. But the DA is the only long arm that I've ever heard of that does.
CV66 if you look in discontinued lines you will see a post I did while back with my beat up steel receiver job. . I did lot more research and emailing around since about no 034 . Wrote to browning etc. Turns out to be they think first week of production so it’s a very early example. People in Ogden advised me story goes Val gave the first 50 out to family members,close friends and relatives and some key dealerships pre Europe release.
