Here are two JC Penney Sportclad Horsehide jackets from the same time, mid-late 40s. The clean one has the original 40s Talon Zipper, the Worn has a replacment Talon. The Unworn is what you would have found hanging in a JC Penney store c.1947. Both have a 40s Sportclad label. The Fronts are probably identical, Square Pockets, breast pocket. I would say the low side buckle jacket is older, the side gathered is the next generation.
