Hey this may help, When I was about 12-13 years old I bought an A500 model it was cut away on both sides of body with an oval soundhole, this was in 1982/83/84 price then was $500.00 at a dealer new, headstock had pearl inlay up the scroll flower design but no double A's. Wish now I had of kept it, sold it to help pay for divorce in 1995.
