Vintage Men's Stratojac Wool Jacket, Trench Coat 40L

Vintage Stratojac Men's heavy wool jacket l/trench coat. Has a faux wool lining, size is 40L. It has a small wool on the inside that can not be seen on the outside. Has some yellowish looking spots on the bottom right side(see pics). I have not tried to remove the spots because I'm assuming it's dry clean only.
