True vintage men’s coat w/faux fur trim XL

This is a fantastic true vintage men’s coat circa 1960s. Amazing Madmen style, think Don Draper! I cannot find a size listed anywhere on this - my best guess is that it’s around an XL (no smaller, as my husband who usually wears a 2X can fit into it, but the arms are too short). Fully faux fur lined, good used vintage condition, this coat is sharp!
