This is the third Concertone (Montgomery Ward's) "parlor" size guitar that I have come across now. This one would have been the top of the line in their 1920's lineup of mail order catalog guitars with mahogany 2 piece back and sides and straight tight spruce grain top with MOP inlays in the rosewood (or is it ebony?) fret board and fancy inlays. I don't know what to do with it other than maybe cleat a couple of tight nonbuzzing hairline cracks in the top. The neck is straight! The action is such that a neck reset would help it be a better player but still marginal.
My question is how do I treat the original finish in order to help preserve it? What do I clean and polish it with? This guitar has been stored high and dry...maybe too dry. What's the best way to treat nice old wood like this?
