Though there is no reprint publisher named and the date shows as 1874, this booklet is far too new for this to be true. I think this is the Ray Riling reproduction from 1960. I had one once and, as I recall, it looked like this. The booklet was originally published in 1874 by the National Armory of Springfield, Mass. The pages are constructed from quality coated paper, including the fold-out diagram at the back. The booklet measures 6"x9-1/2" and has 51 illustrated pages. There is much information here. Very clean with sunning to spine only. former owner's large pictorial bookplate is on the back of the front cover.
