Jerry is on the right track.

This will get you going ...

Buy it or copy those photos before it's gone!

James.

I saved the motor images for you ...

Wow ! Thank you so VERY much ! This is just what I needed to compare my 'inner workings' with a complete, 'put together' working version.

The photographs show exactly the same 'inner workings' - on the 'face of it' - although mine loads the coins from the side so there may be one or two differences ? I will spend many a happy hour figuring out 'what goes where, if I am missing some parts etc. (Like the 'non-return cog').

Oh, and "yes", Jerry was 100 % correct - I should never have doubted him ! Thank you once again Jerry.

So, having had a look at the 'inner works' design and compared, there do seem to be some interesting differences. I wonder if this means that my machine is earlier / later than the 'top coin loading' ones or just a different design ? This needs to be looked at in more detail - a bit like finding an alien space-craft and attempting reverse engineering ha ha !

Any-way, here is my second 'What is this' question:

As shown in the following photograph, my coin op has a circular part below the usual coin slot.

It doesn't seem to be another coin slot though (too large an opening ?) - so what is it I wonder ? Maybe a 'token' instead of coins ?

Thank you once again for any help / ideas with this.

Thank you, sir. You are welcome. I am happy for both of us.

This looks like a bowl niche that likely would have a protruding lever to make the coin pass through the mechanism, something you move with a finger after inserting the coin.
Also, if no-one has told before, the ratchet and pawl retaining mechanism looks like the Garrard system, and that would explain the pin:

Thank you, Inigo! That is the device that I was referring to in my previous comment, but that I could not find the proper words to describe...

...it could be for a device that lifts the pawl away from the ratchet wheel during winding, then pushes the pawl down against the ratchet wheel when the crank begins to reverse. (This would allow the winding process to be silent) Honestly, it's a bit difficult to describe that style.

Now that seems to be VERY interesting.

I can now see clearly how the ratchet works.

Also, although the motor is clearly marked 'Polydor-Aut. 75' (photograph 'below') if it could be a Garrard system / design then maybe there are many similar Garrard motors I can find with the same size 'parts' ? I could therefore restore this area using parts (cog etc) from these motors maybe ? Like maybe a Grarrard 10 or 1a ? I wonder .............. I have a spare Garrard 1a and others maybe.

I will investigate this then.

Thanks again Inigo and Jerry !

Well I had a look at one of my spare Gerrard 1a motors this morning and the 'non' return parts' looked like they were very similar.

The very good news is that all it involved was removing the parts from the Garrard and re-fitting them on to the coin op motor.

The parts (cog etc) seemed to fit perfectly - all they need is a good grease / oil later so they move more freely. (Photograph 'below').

Many thanks indeed to Inigo for mentioning how similar the parts were to a Garrard and 'putting this idea into my head'.

So, moving on to the next thing ...................

Oh, I see what you mean about the 'protruding lever' suggestion.

I need to see photographic examples though to fully understand and investigate further as to how exactly this (maybe unusual) gramophone works to 'piece things together'.

Very interesting as always. Thank you.
