After looking through a lot of old posts in the archives on J.P. Beck guns, I still cannot find a definite answer on the material he used for his nosecap rivets. Were they steel, copper, or brass ? The photos in the books that I have do not show enough of the nosecap to see his rivets or the spacing. I was fortunate enough to handle one of his guns at the Baltimore Gun show a couple of years ago, but did not look at this detail. I am leaning toward steel. Any thoughts ? Thanks, Roland
