Vintage Roebucks Denim jacket size 52

This Roebuck denim jacket is in excellent condition. The color has not yet begun to fade. It is pre-owned but seldom worn. Check out the close-up pictures. They show the condition better than words can. All buttons are in place. Large inside pockets. It is a men's size 52 regular. I'm guessing it fits like an 2X large? It is truly in fantastic condition and comes from a smoke-free home. Please feel free to ask any questions. Thank you for looking
