That looks like a QC54 for sure. $600 is a righteous price with all the tooling and the table. I'd snatch that up FAST before it gets away. I have a TH42 (change gears) and have been given a QC54 that was under water in Katrina. The bed is well rusted, but the change gears look OK and look like that will fit my TH42.(I hope!!) It is a light duty lathe as are all those flat bed lathes, but for hobby work, they are hard to beat if you can get one at the right price.
