That is a 20 g with the wood from a 30/30 h+r with the straight stock.I got the wood in on a gunbroker deal were i needed a receiver and the wood came too ,, so i did some sanding and oiling on it to make it lighter.All H+Rs are the same damed color wood + i wanted to be different.The gun has been cut to 19" about 20 years ago and i must have put 1000 shells down the tube.Its so fun to shoot.All the kids in my familial have learned to shoot with it over the years.Its been a fun gun for the $60.00 i paid for it back them.
