Definitely not an LXM, but not sure what it is. It's a 12-fret model (necked joined at 12th fret), looks like a smaller 0 or 00 body size, probably solid mahogany, other than that ?
Interesting - I think all of the size 5's were spruce-tops. It looks like a 2-17 from the 20's... the right size and color. But the headstock is all wrong for a 2-17 (they were slotted). Not LXM.
