My buddy has a 1957 Browning Sweet 16, 28" full choke barrel that has been used very little and looks very close to new. No sign of ever having any rust. He is thinking about selling it as he's really not a hunter or a collector. He's not hurting to sell it, but would like some ideas on what it's worth. I've see quite a few 1957 models for sale online and on auction sites where they're asking anywhere from $1500-$3000. Also, did any Brownings of that time period come with a vented recoil pad, as this shotgun has one and it looks factory? Thanks for any help!
