'Someone in my home town is selling their El Degas (Les Paul Copy). I'm trying to gather information before going to view/try it. It looks very similar to many of the photos posted in the Forums (black finish, gold twin Hamb. and tuners), escept for the logo on the headstock. I've noticed many differrent pattern for the diamond shape logo. The one I'm looking at is a 4 piece: an L shape on the right and triangle on the left on top and the bottom part is the mirror image with the L almost touching (see picture).

From the Logo shape, can you tell (approximately) when and where (1970's or 1980's, Japan or Korea) it was made?
The owner is asking $275, and the guitar (from pictures so far) looks in very good shape. A bit too good in fact for a 30 year old (unless it's been sitting in a corner of the house for all these years!).
Here's what the body looks like:

Thanks for your help.
Cheers
