𝅺VINTAGE lined military jacket

Jacket is in overall good vintage condition. There is a button missing and the area where the zipper is has a faint pinkish hue. Please see photos. Inner layer is removable. Zipper works. No tag. Measures approximately 35” long and 23” from pit to pit. My guess would be a medium, but please go by measurements. There are two patches- one is South Africa and the other is Hungary.
