H & R 32 ga Special, It's actually a dart "projector". Place an adapter in the bore behind the dart that uses .22 blank to launch it. Shotshells are available for it, probably mirrors a .410.
Jap Arisaka 7.7 rechambered to .308 fitted with a beautiful sporter walnut stock, just original open sights. A cousin (and close friend of my father) had obtained it during his service in the Korean War, and had the work done. He passed away way too young at age 39 and I bought it for $60.00 at his farm auction in 1969. Good shooter, killed my first deer with it at age 13.
