This is one of the first guitars Martin made in 1946 and is essentially a 45 in all respects. Ad top, Ebony finger board and bridge, identical to the 1945 000-21 that I own. It is in ridiculously excellent condition and appears to be virtually unplayed. It has had a perfect neck set, and is an absolute cannon as one might expect. The two things worth mentioning.: the crappy original tuners have been replaced with no alterations, such that the original tuners could be reinstalled. As well, there is a re-glued center seam on the top. It comes with an extremely nice custom ‘pebble’ case.
