I’m looking for some information about this guitar. I bought it in the late 1980s or early 1990s. It was in a small music store with a sister guitar with steel strings, the design was identical except for the necks. I kick myself in the ass for not buying both of them but I was waiting for the price to go down and one day the steel string was gone. The label appears to say C100 ENT and the serial # is LG000063. Any ideas out there?
