Wanted: ✧ RMB-93 (RMO-93) aka Rys aka Lynx russian shotgun with folding stock ✧

Looking for RMB-93 (RMO-93) pump shotgun with folding stock like on the pictures, but will consider other versions as well. I'm a serious collector, check my rating.
I will also consider trading my thumbhole stock version which is harder to find and more pleasant to shoot to your folding stock version.
