Edward, Sid Vicious was mostly pictured wearing a Perfecto style jacket although whether it was a Schott or not I don't know. He defo wore something similar to a Highwayman which was covered in studs but I think it was a Lewis Dominator. There's even a pic of him wearing a two tone biker jacket.
Mn, that Rivett's Highwayman could look really sharp in Cordovan.... (or for a more early 70s look, that blue hide that MajorMajor had the Aquamarine in...).
I think Cordovan looks better on a slim fit jacket, but that highwayman looks like a relax fit, I think black will do a better job on it. Just my option.
I just had a riffle through the really new designs. and the only half-belt design I saw was the Plainsman, which is a LHB without the cargo pockets. But I do know that they have done a set of 30s jackets redesigned with slimmer arms, higher arm holes and longer bodies.
