Vintage men’s vest, wool?, brown, 4 pockets, 6 buttons, size M?

Awesome men’s wool vest with 4 pockets and 6 buttons! These features make this vest anything but ordinary. Brown wool with very thin cream stripes. There are no tags, so I don’t know for sure it is wool (but it does feel like wool). Silky back (probably polyester). No size given, so please refer to measurements below. This would be a terrific piece for any gender! In excellent pre loved condition! 19 inches pit to pit 26.5 inches length
