Here are some pics of an old tailstock that I found.  
I was hoping someone would be able to identify it,
  as to what make of machine it came from.
It has a 7/8" bore to accept tooling.
It came with a recessing tool or something, that 
   might be used on a turret lathe.
The tailstock is rack and pinion feed.
The small lever is a ratchet clicker of sorts.
There is a spring that retracts the ram when you
   pull the small lever.
The casting says, "BM-1000" on the body,
   and, "BM-1010" on the top cover.
I plan to make an adapter base plate for it,
   and use it on my 9" SB junior lathe.

Any help in identifying it, send me mail at
   doozer75@roadrunner.com

Thanks-
