I'm pretty sure this is a rebadged Lathe & Morse Makers - possibly even Shepard, Lathe & Co
It is virtually identical to my S,L&Co.
To include:
"Moulded" bed full length (difficult to pull from drag/cope)
Rise & fall on a crank handle,
Weighted saddle
Right/Left worm in the apron to change carriage feed direction.
"Flat-Top" tailstock (with replacement hand knob - a common repair for the somewhat easily broken cast iron "T-handle."
Rear-mounted lead screw.
Shape of change gear "knobs" that hold them in place.
Shape of carriage feed knob
Shape of leg cross-stretcher, and where the webbing hits the leg relative to the cross-stretcher (fairly high)
The only feature I see "later" (leading me to Lathe & Morse MAKERS - 1864 to 1871) is the shape of the tailstock on the back-side of the box. Earlier (like mine) has no "ovolo" curve here - my tailstock box curves gracefully in an "S" between the taper slide and the lathe bed -- this one has an "ovalo with detent" shape. A little later and by 1874 L&M changed to their "shelf" modus. This one Middle range on type study.
It seems to have the remains of the original countershaft. Hangers are original(square shifter rod holes), probably also the cone pulley, probably NOT the single clutch which appears to be a later setup and does not utilize a shifter rod/handle in lieu of handle alone..
Best offer is hard to beat - well maybe if you REALLY want the legs to make your $1800 "industrial table."
I hope it goes to an interested home COMPLETE. Certainly among the 1000 oldest lathes extant in the country.
