Late-1970s Schott Perfecto with the bull label. Black leather, asymmetric zip, quilted lining, zip cuffs, slim cropped late-70s cut. Schott didn't print the model number on the pocket tag before 1985, and in the late 70s the 618 (finished steerhide) and 118 (naked cowhide) were the same jacket apart from the leather. The previous owner believed it's a 618.

Size: 36 (early Schott sizing runs smaller than later 36s)
Measurements (inches, laid flat): Shoulder 16.5 | Pit to pit 19 | Waist 16.5 | Length 23.5 | Sleeve 23.5
Condition: Vintage. Half belt was removed by a previous owner. A few small holes in the lining at the right armpit were stitched closed by a previous owner. All zippers, pulls, chains and rings present; no open seams. Normal leather wear with creasing and light surface scuffs consistent with age; see photos.
