1932 Martin C-2S 12 String Guitar

Martin produced only six pre-war twelve string guitars.  This C-2S was the first.  The three flat tops were less successful. 

As the "new Longworth" book says:

"Given the light construction of it's flattops at the time, adding extra strings to a C-2 was probably a better choice."

This guitar was formerly owned by Mark O'Connor and used for his "False Dawn" CD.
