This old gun sat in my Grandfather’s gun cabinet when I was a sprout. My father gave it to me 30 years ago and I’ve kept it oiled, thinking someday I’d do something with it. Reading a recent thread about barrel lining, I pulled it out and looked it over. There are no makers marks on it. On the top of the barrel is a stamping. “Rebored & Rifled by J. Stevens A & T Co., Chico???????, Mass. I did some measuring and research. It seems to have been rebored into a 25 Stevens rimfire chambering, long out of production. It has a nice double set trigger. I’m considering having it lined as a 22 LR, but the “ejector” might be a problem. Thoughts?
