1910 catalog here.
Sebastian built lathes from 1891 till 1951, when they were acquired by Cincinnati Metalcrafts. I have not seen an actual Sebastian lathe but according to Vintage Machinery.org. the company was started by Benjamin Sebastian and his wife Clara after he left the Sebastian Mays Co. in 1891. The company was located just across at Ohio border at Covington, Kentucky.
Upper right corner, on the back gear, wonder what those segmented teeth are for?
Update; Anonymous in comments suggested it was a tooth repair using round studs filed into the shape of the teeth. Very interesting repair.

The only thing I can think of regarding the gear is that the segmented area is where you put grease, so it doesn't get immediately squeezed out and has a chance to distribute?
my guess is a couple of teeth got broken and were replaced by tapping threaded studs in and filing them to fit , a common repair to cast cogs in years gone by.
I abandon my suggestion and second the repair solution. It looks like typically they would fill in the space between the studs with weld and then file to shape, but that step was skipped. That repair took some skill and patience.
I'll check it the next time I'm there, won't sell quick I suspect. I'll take better pictures of that area.
I took better pictures and yes absolutely, repair job, 8 round pins fastened in place and filed into the tooth shape.
Very impressive.
