I love the high end used equipment market.

FFFFFFFUUUUUUUUUU
Old nothing, I
WISH I could get a 30-40yr old lathe built in the czech republic. Those things are TANKS.
We had a REALLY nice TOS lathe back in college, bit of an oddity really. 6" chuck, 6ft bed and heavy duty tailstock. The headstock was about 16"x16"x 30" long. It was just 2 sets of bearing with a large hollow shaft, belt driven from the transmission that was in the base of the machine. 10hp motor driving what seemed to be a vehicle transmission with a rotary dial style gear selector. The gearbox for the feed was where it usually is under, but just infront of the headstock.
It had a mechanical brake (the best system IMO), feed direction change lever on the saddle and headstock, adjustable friction clutch on the saddle, the whole machine was a single piece casting and INCREDIBLY accurate. I just found it strange it was a belt drive to the head and a 6" chuck for a 10hp machine.
The best part is that because it was so big and didn't look as simple to operate as the other machines, most students never touched it
Now I'm rocking a P.O.S. nardini 4pc casting brazilian lathe with no friction stops, a broken power lever forcing us to turn it on and off via the emergency stop, and active braking on the motor that stops working when the motor gets to running temperature.
EDIT; found pics!
it's a TOS trencin SV18, the college had repainted it all in a nice dark grey and it was really clean lol

These last two are the exact proportion of the one we had, but without the dial shifter for the transmission
