Here’s a 00-21 from Martin’s old North Street factory era, made a year before they moved into the new factory. Although it has some “modern” features, it was made in much the same way Martin had been making 00-21 models for the previous 100 years, such as using hot animal hide glue and quarter-sawn Brazilian rosewood back and sides, with very straight grain and wonderful color. Here’s the story: The top and neck have been refinished, while the back and sides appear to be original. Bridge, pickguard, and tuners are original. There’s a plugged hole below the endpin, in the end wedge, where a pickup jack was removed. There’s also a small hole in the upper (bass) side near the neck heel, from a strap button. Also the crack in the top, which has been glued and cleated. New frets by Gryphon, and we also refinished the headstock and gave it the correct size Martin decal (the original decal disappeared when the neck was refinished). There’s also a tiny filled area in the neck, just below the seventh fret. Yep, it’s seen some changes, but it’s an attractive Brazilian rosewood Martin from the early ‘60s that plays well and sounds great.
