This jacket was made by Himel Bros. Leather of Toronto, Canada. It is their Chinook model, with a double breasted closure, shawl collar, handwarmer pockets and flapped cargo pockets. It has bi-swing shoulders, a wool lining and deco vintage buttons. This was a pre-production prototype, with more detailed surround stitching on the handwarmer pockets than the production version, and no tag.
