Harris Tweed Jacket

This is from our Father's closet. I suspect it's from the 1990s. It has a union tag in it which might help someone to age it. It's in quite good condition except for the one little slit that has developed in the back of the lining. It is a gray Harris Tweed with small lines of blue, yellow and red running through it. Measurements p2p 22 " shoulder 19" sleeve 25 " shoulder to hem 31" Our Father always considered himself to be a Medium.
