I know, the threads old, but I too found one on craigslist and am curious. I believe it to be a '79 MG300. I got it with no parts except the brass nut. Took me about a week to get it put together and it's become my main guitar. I'm curious as to the wood. I think it's mahogany, but could be wrong.
That's really all I could ever find since they are, once again, making guitars, I can seemingly only find the new ones while searching.
