Tools for Repairing Marine - Naval Sextants

We stock Bristol Spline Keys for the repair of Link A-12 Bubble Sextant.  Most of our 'sextant' customers purchase the Bristol SS-508 - 9-Piece Spline L-Key Wrench Set.

The correct Bristol wrench size to fill the bubble assembly is the third largest one available in the SS-508 SPLINE KEY KIT. It is the 4 flutes key number S-076-4. The largest key of this kit, the S-111-6, is also the best suited wrench to slacken the index mirror fastening screw on its axis in order to perform the index error coarse adjustment.
