1970/80s vintage wool jacket. Size large.

Vintage gray heavy coat with marrón lining. Six buttons down the front three on each shoulder. Has a piece that comes over the front and down the back, almost like a smock on both sides. Size large. Chest 26.6” had extra room in the sleeve/armpit area Waist 23” Length 41” Material tag and brand name label are gone. I am certain this is a mostly if not all wool jacket. Every time I get around it, I start sneezing. The only issue I see on this jacket is there are some white specks on the inside of the left sleeve. It might be paint. I had it dry cleaned and it’s still there. Not very noticeable. Please see last photo.
