Interesting unit

Very different. Not obvious how the cross slide works or where the adjustment is. Also why two different height tool holders!

And just look at that tailstock! Wow.....

For 500 asking, I'd love to go and see it but Cornwall is waaaay too long a drive.
 
Turret lathes are fascinating machines, but really orientated to (pre CNC) production parts vs general purpose lathes. Some videos of the big brothers which have more features.


 
@johnnielsen has a large VDF turret lathe, and is quite useful for turning anything less thatn 24" long. I guess it has a swing of 20" - the 3 jaw chuck we just rebuilt is over 14" in diameter... So in the 14X24 footprint it is a general purpose lathe.

The cross slide can not move longitudinally but moves the cross slide tools toward the piece being machined via the handle at the left front of the cross slide.

I agree that turret lathes are designed to produce multiple identical production of parts. Saying that, I have used numerous turret lathes with a travelling carriage and power feed to make single parts as well as production runs. If you do your threading with taps and dies, then a turret tail stock is ideal. My favourite thing about turret lathes is that I can install a centre drill, a spotting drill, pilot drill, a finish size drill, a live centre plus a tap or die for threading and simply rotate them into position as required. There is a reason why CNCs also use turret style tooling.
Some don't mind cranking the engine lathe tailstock in and out to change tools but I find it pretty tedious.
If you have a fancier one it will have a threading transmission and then you have the best of both worlds. For instance, my VDF will do 112 different imperial threads from 140 TPI to 1/4 TPI.
The only thing turret lathes are not suited for is machining long shafts between centres as they have a shorter length capability.
