K& e double sphere optical square # 71-2412 very nice
The 71-2412 is very similar to the 71-2410, but differs in that it has a second sphere machined behind the front sphere which has the optical objectives mounted in it. This allows the rear sphere to be mounted in the K&E cup mount, and then rotated 360 degrees with unobstructed views through the alignment telescope on which this is mounted.. THE SERIAL NUMBER IS 152413. WE OFFER A DOMESTIC DOA WARRANTY . LET US KNOW IF YOU HAVE ANY QUESTIONS. THANKS FOR LOOKING.
