I'm assuming its between about 14" and 18" long?
FH doesn't bring up anything other than a few model numbers.
I would guess its a self-made lathe as although the bed looks well made it might be over-engineered and the very hevy stock plate used for the saddle and tailstock are crude in contrast.
The pantograph may be original as the relatively massive tailstock base is out of proportion to what I would expect. Also the top face of the tailstock does not look like it is designed to have a normal barrel assembly fitted.
So, my guess is that it is a 'special' built for a particular purpose, perhaps it was a small copy turning lathe or even a special for turning convex/concave surfaces?
That said, the well aged and still in good condition base casting could prove the basis of an excellent small lathe.
