I've bought a few weeks ago a The Martin tenor that seems in mint conditions and plays, oh boys if it does play! Compared with my other Martin, a Committee II, it has that tiny bit of added punch without loosing the typical Martin darkish sound.
I have been told the lacquer is the original one, and by the look of the case (original too, and in mint conditions) it could be true. The engravings are gorgeous, and everything is smooth (apart from the Bb palm key, that need a bit of adjust). Only spot of an otherwise spotless instrument, the "hissing A syndrome" on A second octave, probably needs some pip vent trimming.
Serial Number is 204xxx, so it's a 1958-1959 old guy, but with an incredibly young look!
