The lathe came to me with the following gears installed:
Output gear from headstock 40T keyed Idler gear on banjo 70T, bearing in center Input gear to QC 40T keyed
The extra gears are,
I can't figure out when and how these should be used. This lathe is probably similar to an older Jet 10x24

Metric. I have the same machine and mine has decals showing different tooth ratios for metric threading. I've used the gears to cut an M.5 thread for a microscope adapter. As I recall, I used the 39 and/ or 43.
Not saying this is it, but my lathe came with a group of metric gears. Could that be it? Just guessing.

Any chance you could scan a manual for me?

The description of your gear train seems rather different from the ones I am aware of on these kinds of lathe. Most of these lathes have two large gears on the same shaft in the middle with 120T and 127T. Here's a link to a manual that is similar to the lathe I have...
What is the leadscrew on your lathe? Is it 8 TPI?
Probably not. While the exact English/metric conversion requrires a 100 and a 127 tooth gear, these are BIG (and expensive). A very close approximation is obtained with a 37 and a 47 tooth gear. The result is close enough unless you are threading a very long piece.

Rex, I just found this board today and your old post here. Pleas contact me if you are still on the board. I too have an Enco 1024 and am seeking parts help for it. I will keep a watch for you here. Thank Ric
