Yes a Mascot, in the 2 to 2.5 ton range, 3 1/8" spindle bore, 17" swing, that one is a straight bed, various RPM ranges the best topping out at 900 rpm, so if you want to make a lot of smaller parts it won't be as good.
At least 50 something years old and it looks pretty crusty and unused for a long time.
In reality if its a good lathe or not will come down to condition but you won't know until its been cleaned and you can properly test it.
Best you can do in that state is have covers off and inspect everything for obvious wear and damage
^ This is correct! That one is the "Dominion" model, ie short bed, without the removable Gap, and the carriage and tailstock are lighter built. The large bore on the machine and the low RPM (26) is a very nice machine for some heavier work. That one looks to have the 2 speed motor control so hopefully it still has the original motor too.
I have the Mascot "Mammoth" in my shop, and it has the removable gap bed, 80" centers, and the carriage is setup for T nuts etc for using it as hz boring / milling setup. Mine scaled in at 5200 lbs with the chuck and tailstock on it. I have a Youtube video of moving it when I bought it a few years ago.
I have used mine for all kinds of work so far and it was / is pretty much my Home shop dream lathe. I started out with a 15" Triumph gap bed model, and then picked up a 6" student (12" swing) and then sold the Triumph to purchase my Mascot Mammoth.
Turning a set of Ford SD 8 on 170 to 8 on 200 dually hubs into 8 on 170 to 8 on 6.5" dually adapters.
However, the removable Gap bed is very nice for the few times you need it. I have a 26" diameter faceplate for mine that gets used occasionally. I needed to turn a different taper in this compressor wheel than what it had originally in order to run it on a different pump.
If the bed isn't damaged or horribly worn, that lathe is worth the current asking price.
