I recently purchased a Montgomery Ward's / Logan 10" lathe. Included in the purchase was this beauty. No name stamped on or cast into it, just the serial number 00042. Some quick googling came up with a few links:

The dividing head had been modified (not permanently) with an external gearing system which effectively changed the input/output ratio from 40:1 to 12:1. It also has a collet adapter for the cutest little collets I've ever seen, a 1/4" Levin D collet (which based on Levin's website, goes for $365 for that collet alone...), a matching collet draw bar, and a spindle thread protector.
I tore the whole thing down, and cleaned and oiled it. Looks like it's had very, very little use over the years. And whoever had it before me took extremely good care of their tools; not a speck of rust on anything. It's fully functional with little backlash in the gear train. It's missing two dividing plates and the sector arms, but appears to be otherwise complete.
Anyone know anything else about it? Like what's the spindle taper?
Based on some of the other equipment/tooling that came with the lathe, I think the previous owner used it to make small involute gear cutters for clocks or watches.
All the best,
Jeff
