As you've established the quill moves freely in the tailstock, the problem lies with the stuck thread. Probably what has happened is that the thread has been wound all the way in and is just locked tight. I suggest you refit the quill in the tailstock, replace the grub screws and locking screw then try applying more pressure on the handwheel to free up the thread. You will probably find as soon as it moves, it runs freely. I have come across other lathes where the thread locks if wound all the way back in.

You probably need to rotate the handwheel clockwise (looking from the back end of the lathe) to advance the thread.

Sorry forgot pics again.

Chances are that the outside of the quill has rusted and attached itself to the tailstock.

1 Take the grub screw out of the wheel so it comes off (normally a push fit weld by a grub screw onto a flat)
2 Remove the lock screw (normally on the back of the tailstock, if it isn't obvious can we get a picture of that side please)
3 Try to unscrew the drive screw from the back end (should come out once the wheel is off)
4 Use penetrating oil and a mostly safe drift to get the quill out. A rocking motion of 2 taps from the back and one from the front should get you there
5 Clean everything and re-assemble.

Some grease on the thread portion is OK, between the quill and the tailstock I prefer to use machine wax as it doesn't collect sawdust.

Look forward to your progress report

Also not sure on the lathe single bar lathes were popular back in the 70's but I don't know this one!

As above the wheel should move the quill in and out, once it is free look for a grubscrew holding the wheel to the shaft and you can remove the entire assembly for cleaning.
