Vintage 80s Couture by J. Park black leather jacket with detachable wool lining

This jacket is major - nice heavy leather, detachable wool lining through the body, super well-made, outstanding vintage condition - FIL's closet and I'm pretty sure this was barely worn. Front zipper and button/snaps, two outer pockets and two breast pockets. Size 48, but who knows what that meant in the 80s, so flat measurements are pit to pit 28", shoulder to cuff 28", waist 27", shoulder to hem 35". Thanks for looking!
