I found this all-purpose utilitarian sport jacket pictured below at a thrift store. Feels like steerhide. Black quilted lining in the body and sleeves. Knit wool cuffs and waistband. Two open hand warmer pockets, one zip chest pocket, no interior pocket. The leather is in very nice shape. No cracking. The only tag is in a pocket, marked size 46 with an illegible model number. The jacket feels like a size 44-46. A size 40-42 could layer up nicely in it. Cuffs and waistband are in really good shape with no holes. Comfortable to wear. Main zip is a old Scovill "Gripper Zipper" and works nicely. Chest pocket has an older diamond-shaped Talon (first time I've seen one of these older Talons in the wild). When I see a diamond pull, I immediately think 1940s, but I'm not sure if those pulls extended into the 1950s. The tag reminds me of vintage Schott but I don't know if other brands used similar tags. Any idea who made this jacket? Era when it was made? Maybe @tmitchell59 has some insight?
