Astro Compass base

A base to hold Astro Compass MKII. Note that I do not have the holes for traditional mounting on aircraft, as I imagine most people tinkering with these are putting them on tables or mounting them on tripods. So I have a big flange for table top use and a 3/8' threaded hole in the center for tripod use. Of course, the threads are plastic, so use at your own risk. It does have the "AFT" marking on the base as well as graduated witness marks.
