Sorry I didn't take more time for a proper response
I'm looking at 2 very wise choices for a home shop mill and a lathe and I'm thinking the guy knew his machines pretty well. Yes they have been neglected and it will take some investment of time and energy to get them back to pristine looking condition. But the person who knew enough to purchase
those 2 machines most likely knew enough to avoid any thing that clapped out from decades of production and abuse.
Not that I'm saying don't take your time to thoroughly inspect them - just that other then some dirt and slight surface rust - I don't think you'll find much wrong with them.
The 1 thing you want to ask about on the lathe is if he has the "Steady Rest" for it. It will look some thing like this one
and with the milling machine I see 1 collet in the machine but he should have the remaining set of collets and perhaps a milling vise to go with it. They'll look some thing like this
Also since he selling off the machines I would ask if he has any tooling he wants to let go of too.
Now you could make the same mistake I did and spend less on "Better Looking" Asian machines and "Think" you got a good deal. But after fighting loose tolerances, soft metal, indicator dials basically lying to you (turn dial .030" and tool moves .035") if you really want to make any thing of value, worth having - you'll end up "Upgrading" to 2 machines like those
