I’ve never seen another jacket like this.  It’s brown corduroy with patch pockets and a dinner jacket style shawl collar. Part hollywood jacket, part tuxedo, part smoking jacket.   It has a link style button closure with shiny brown sportswear style buttons.  It is unvented and has no buttons on the sleeves.  The jacket is fully lined, with one of the coolest labels I’ve seen.  The label states that the jacket was styled by Devonshire of Toronto, and the brand is Du-Val (The Most Durable Values) established in 1924.  There is a small spot on the left shoulder seam where the stitching has let go, but that would be easily mended.
