Petermann Watchmaker Clockmakers Pinon and Gear Cutting Machine

Hi guys, have picked up the following items. looking at lathes.co.uk i believe its a automatic pinion and gear cutter from Petermanns

I am looking for a manual, that may have a parts list. i would like to see what is exactly missing and how it all works as iv'e seen some versions online but there are differences.

I would love to get this working again , it's very impressive

I have a fuller machine and another machine that looks like its missing a lot as backup along with a hand wheel.

I know i need index plates , can anyone one tell me what these would look like in order to try and replicate one to test the machine on .

Any help will be appreciated , there are a few bits online , bit nothing with parts , instructions or ideally servicing guide

Thanks in advance.
