I've owned many vintage jackets and fix very few..it is very expensive to have jackets repaired. Rotting, flaking, cracking of the leather shell is when I do not buy. This is most prominent on the upper arms and shoulders. Both are high stress areas. Some shoulders areas an be reinforced through an inner piece. I don't think an upper sleeve area can be so reinforced short of a new sleeve. This is a very interesting California Sportswear jacket that can not be restored. It is currently with Dave Sheeley being used as a pattern/model. He called this "red rot". It is goatskin. This is a Levi made jacket. An original "Speedway" as named by Aero. It is worth restoring. It needs a few areas re-sewn, but does not have rot. The lining is pretty well ripped. A lot of folks would pass because of the lining. I don't care that much about worn lining even though it is expensive to replace. The point is it can be replaced. So can zippers and seams re-sewn. I can't wear it do to size. So down the road another owner may op for a restored lining. When the leather shell is gone, so is the jacket. Linings, zippers, buttons, threads can be repaired/replaced. You have to figure if it is worth the cost. I guess it is just a personal thing.
