turret tail stock help to id it

[1yesca]

so i have had this turret for some time and i just finished putting together a clausing 4800 12" lathe that's been sitting for about 20 years i set this tail stock on it and it looked good except it was about 1" low center to center looked good also there are no makings on it at all any ideas ? yes its set up for an 11" swing and a new bottom plate could be fitted to it to raise it up but !

I don't happen to know the bottom contour of mine offhand, but I've got a very similar one sitting in a storage unit awaiting "someday" to be adapted to my 16x40 import. I don't recall who all sold them, but there was a period (before CNC) when you could buy these on the aftermarket, usually with a selection of bases fitted to popular lathes of the time.
