The Hofmann rotary table was available in two guises, one has division plates and the other has a normal graduated hand wheel.
I have the 8" division plate version myself and agree with you that it is a superbly made bit of kit.
When you get one, let me know and I will send you a spead sheet showing all the available divisions and the number of holes in the plates etc.
There is a 10" one on ebay just now.
