Vintage rubber and canvas rain jacket

Vintage rubber and canvas rain jacket. Firetruck red rubber with navy canvas lining on inside. Snap buttons - all functioning. Very great used/vintage condition. There is a name written on inside, the stitching at the pockets is a bit loose, and there are a few tiny white marks on the back. (Shown in last 3 photos) None of these minor flaws affect the rain proof qualities of this jackets and are only really noticed if you’re really looking for them. No size tag but I’d say it’s fits a S-M
