Vintage unbleached bone guitar nut, Martin style, 1-11/16" width, flat bottom, slotted

This unbleached bone nut is prepared ready for installation in Martin and similar guitars. This style of guitar has a nut with a flat bottom but angled ends. Having these ready cut to the correct angles takes away much of the time needed to prepare a new nut blank. And the slots are accurately cut too. It has the narrower Martin spacing used on most Martins since the late 1930s (1-11/16" rather than 1-3/4" neck width). You just need to do final fitting.

1-11/16" neck width, flat bottom
1-23/32" x 13/32" x 1/4" (43.49mm x 10.29mm x 6.35mm)
18" (457.20mm) top radius
1-15/32" (37.21mm) string spread

Bone sounds better and lasts longer than synthetic alternatives, and as unbleached bone is harder and more durable than bleached bone you get the best possible option. And it looks suitably 'vintage' too.
