Vintage 70s/80s Global Identity G-III Leather Bomber Men’s Size Medium GUC

This is such a cool jacket. I’m pretty sure it’s a military bomber jacket? But not 100% sure. It has a 100% Leather Shell with discoloration and a few stains that’s are super noticeable. There is a pretty dark stain on the inside near the right sleeve maybe 🩸???? Tagged a medium but likely men’s size medium so close to a women’s XL. Has a hidden inner pocket! Could use a leather treatment and a cleaning!
