hi. not sure abt vintage shops but there is one in holiday plaza. its right on the last floor of the building near the nail/spa outlets. its also in front of a big book store which sells chinese comics/books.
saw a couple of gibsons on display. good luck but i think you'll find more choices in KL if you're in MY.
er...KL im not too sure but i can ask around for you. Let you know next week
