The Gulledge Machine works could be the original name to the Ellis brand before a name change. Go back and see if the guy has the other two index plates hidden down in his basement. May have gotten over looked when cleaning out. Just a thought. Very nice find you have there!!!!
Wow! A lot of money but worth it.Mark,
Someone just sold a Mint Ellis dividing head over on another forum. It had all of three plates, a six-jaw Buck chuck, 3C collet setup plus a bunch of collets and original tailstock. Sold for $400!
Although it is not an Ellis, it is very similar to one. I checked and it does have a B&S #9 taperAccording to the docs online, if it's like an Ellis head it might have a #9 B&S taper.
