Good luck on finding the mount. The sextants used to be pretty common on
ebay but they are rare. The mount was very rare and I waited many years
before I found one on ebay. I suggest you place the sextant on your
ebay notifications and hope that a mount eventually shows up. 

Or, you could visit the Reagan Library in California, break into Air Force
One and steal the mount from the overhead.

I have all the manuals for operation of the sextants and the mount. 





If you need a 28 volt power supply for using your sextant at home
just go down to Home Depot and buy a water sprinkler system electric
transformer which puts out 28 volts and is cheap.
