Byers Series III declination housing w/ shaft and bearings. Cosmetically blemmed on threads outside of useful area.
First $2500 can have it, including all shipping to anywhere in the continental USA. This is a very small fraction of what this is worth. This was previously listed at $3200, it must go. Ed Byers no longer makes these mounts or this casting. Build yourself a $40,000-$60,000 mount with this impossible to manufacture declination housing. The hardest part of the mount (this casting) is made and machined.
Email if outside of the USA. Will ship to most of the free world, you pay shipping.
