Yeah, I've got a very similar set except the side plates are different. Matthews been "working" on the quinto for about a year now, probably avoiding it, it's in pretty bad shape.

All I know about the drums is the badge says R. Galvan, Monterrey N.L. Mexico (nuevo Leon) They're very heavy, put a new skin on the tumba (12") and it sounds pretty good, typical oak, kind of bright. Here's some pics, I'll probably send the tumba off for repair when the quinto comes back, although it's definitely in playable condition.
