Hello and welcome.
I had one of those years ago, you may have trouble getting literature or an original chart they are rare as rocking horse poo. You can calculate it but you need to know the TPI on the screw and the spindle gear, Do you have a full set of change wheels? Anthony.

Here's a somewhat complex spreadsheet from Conrad Hoffman that you might be able to use. The change gear section is on sheet 4. It looks like you can plug in values suitable for your lathe (leadscrew and tooth counts).

Could you take a couple of pictures of the end of the lathe? If you use post #1 as a reference, I think we would want a picture of the left end of the lathe. Probably the best pictures would be with the "cover" off to show the gear train between the spindle and the lead screw.

The chart is saying to stack 20:30 tooth gears for an 8 TPI thread, with a 40 on the spindle and 60 on the leadscrew. When you get it setup, run a scratch on some scrap and use a thread pitch gauge to see that it's right.
