Hey all, I just picked up my first vintage leather jacket and I have a ton of questions. This forum seems like a huge wealth of information and I've learned so much browsing around. From what I can gather, the jacket I have is a 70's era Schott cafe racer(based on the large, chunky Talon zipper with "T" logo on slider stop) but it appears to have been heavily modified (no tags/labels). I think the lining has been completely replaced in addition to the pocket bags and perhaps the cuff zips as well (they are YKK). It is not in good condition but I love the lived-in and distressed feel. My Questions: 1) Does anyone have a better idea of the date? Or the style # of the jacket? I understand without any tags/labels this could be very challenging. 2) There are 7 rivet holes in the shape of a triangle on the left chest — any idea what these might be from? 3) The leather feels pretty supple in general, but the jacket is pretty old and beat up. I've read lots of contradicting opinions on leather conditioning. I would mainly want to condition this jacket to help preserve it but I definitely don't want it to lose its beat-up character. It also is pretty squeaky in the arms and I've read that conditioning will help with that. Opinions on conditioning this jacket? 4) There's a pretty big tear in the lining near the right armhole. Is taking it to a tailor the best way to repair this? I'm pretty handy, could I do it myself as well? Thanks for any help you can provide!!
