If you reline it, and put it on Ebay to let the market decide, I doubt it would bring $1000. With used jackets that's about the best indicator. The facts that it is "repaired" with a replacement liner and with it having no original label are marks against it unfortunately. Walk into a shop in Japan with it and that may be your best bet but who can justify that in the sale price?
I've not watched all the vintage jackets that sell on Ebay but I'm not sure I've seen any similar jackets bring that much.
Now if it is a smaller size, the market will be more limited.
With the shipping scare Platon posted about, I, for one, wouldn't risk too much in an overseas purchase.
Great looking jacket for sure!
Keep us informed,
