I am looking for the approximate price of a Gibson Les Paul guitar in mid-70's Britain, specifically London. My character is in a poverty-stricken punk band circa 1976, and I need to know how much he might have to pay for his instrument. The line is going to be something like, "He'd paid __ bob for it, and no one was going to take it off him without getting their teeth pushed down their throat."
I've googled "price of Les Paul guitar, Britain 1970's" and "price of guitars in punk era," but all I get are today's prices for guitars made in the 70's. If anyone, can help, I'd be very grateful!
