Help Identifying Classical guitar

[bullvine]

Hey there I'm trying to identify a classical guitar I bumped into it at a hospital resale shop it was sitting in a small worn guitar case. The guitar is mahogany and cedar it looked to be quit aged but in solid shape. the finish had a good bit of rash but no cold checking. the only mark I could find anywhere on the guitar or case is a dark MN with a circle around it stamped right on the wood inside the guitar hard to tell if its a ink stamp or burned into the wood.

when I do a web search of MN classical guitar or Flamenco MN guitar all I come up with is a bunch of Minnesota guitar links and stores.

thanks for any help...
