I just got mine but it came from a TWA plane. I came with a sextant that has no averager and stranger still, the mount has an odd modification. The sextant is fixed to the aximuth ring on the mount. When you crank in the true heading, the sextant spins in the mount. The whole thing is a well built locking mechanism screwed into a slot to calibrate the heading using the machined in the mount. It even has a 10 degree fine adjust the initial setting to the tail of the aircraft. There are detailed instuctions in the box. Do you by chance know anything about this?
