They are more a cross between electronic & automotive but as a first draft it works, both are in PDF format.
All I have to do now is to work out how to post them!

I am in the process of drawing a mechanical drawing showing where the various parts are located & their pin numbering.
I have had to make some abitrary pin numbering decisions, not to be awkward but more to differentiate the parts to possibly prevent wiring errors.

Do please bear in mind that my set had been "got at" but a long time ago (1950's) which would indicate that it did still work afterwards.

If you can see any obvious errors then please let me know so that I can correct them.
I must admit that some of the circuitry has puzzled me somewhat!

Thanks go to all who have contributed & offered advice.
