I got this Buddy Charlie off eBay some time ago.
He was wearing a Hasbro Japan uniform, but had a Marx uniform in the box. After a thorough cleaning of a half-century of dirt and cigarette smoke; I gave the Hasbro uniform to a PH Joe; and the Marx uniform to Charlie. It's not an exact color match between shirt and trousers, but I think it gives it a field worn look.
With the frigid New England temps, I've given Charlie some thicker outer wear. I also swapped out his arms for repro Captain Action arms.
