The shirt I gotta give to swath 2. Going by film pictures it’s closest match. There’s a pic of a prop that shows it’s a little dark, but that might’ve been one shirt while the others are lighter. I’m not an expert but going off the screen grabs, definitely 2.
The jacket...it’s tough. None of those really look right. Some scenes looks darker than others, but if you go to Wested Leather Co. site, it’s a medium brown. Reading the material was lambskin called authentic brown....which isn’t extremely helpful lol.
EDIT: This is what they have on Westeds site. I’d imagine oiled and distressed, it’s spot on and, allegedly, made to the exact specs of the Raiders jacket(they weren’t Wested at the time; Leather Concessionaries).
