Don't remember what I paid for it in the late '60's, but it wasn't much. It was a Stevens 311 (with the Sears name on it) twenty gauge side-by-side, 28" full and modified. Double triggers, extractors only. Very plain Jane indeed.
It became my all-time favorite shotgun. It swung very naturally and took a boxcar load of doves and rabbits for me. Wish I still had it.
