    I suggest that Ken Gebhart from Celestaire would be able to field this one.

    Subject: Link A-12 bubble sextant adjustment
     

     
    Hello Group,
     
    I recently bought an A-12 Link bubble sextant but the Instrument seems to be grossly out of adjustment (not surprisingly for a 67 year old instrument). Therefore the index error needs to be adjusted.
      
    Would you know what kind of (hexagonal?) wrench is to be used to adjust the index mirror of a Link A-12 bubble sextant?
     
    It looks like an hexagonal allen wrench is convenient. However metric keys do not seem to be adequate and SAE 1/8" seems too big and 1/16" too small!!
     
    Does anybody has any clue about this question?
     
    Jean-Philippe
