Have had several of these over the years and find them very handy multitools. This one is the Savage O/U 22 lr / 20 gauge magnum 24 C or Campers Companion. Interesting trap door and storage in the back of the stock for ammo -both 22lr and shotgun. Used for many, many animal including ptarmigan, rabbit, grouse, duck, geese, a caribou with a brenneke slug, etc. easy break down and fits in a little case. Trade off is with the 3 inch magnum shells no easy way to put a pad on the back without losing the storage. Sadly no longer made and the current ones I have seen quality control issues - as in hammer not staying back on cocked, and only 410 lower. Hope to pick up a 30-30/20 gauge or 223/20 gauge as well. Nice around the cabin firearms or leave it in the small plane kit, or first firearm, which it was the first long gun for me. Alaska handy multitool.
