My brother-in-law wants to give me a BL-22 or a Marlin 39 A. This Browning has never been shot and he has the box at home. It was my father-in-laws and was purchased in the early 70's. Which gun is considered better (I'm leaning toward the Browning)? Also, the number on the underside is 71(3,8,orB)56693 and this doesn'seem to match the Browning serial number chart I saw. So, I'm thinking maybe its a 1971. ? (I have sone pictures but couldn't figure how to post them).
