I do have a shooter which I presume is German but made for the British market, as on old penny, and has the word light on the gun slot casting. Any connection to yours? I am looking for a gun or a picture of one for this.

I've got one ruining an early Jennings. l quite like it really.

That's correct, also the coin chute which sides on top of the jackpot is wider. I seem to remember that the front casting is also deeper, I think!

let me know if you need more pics
impressive mech, forgot to mention the features, skillstops, venders,gold award, future pay and a handle to operate mech outside of case

Finally dug out the J&M Giganta. Got to say that it's well engineered and different from the usual mechanisms.

Size of cashbox is 200mm X 95mm X 100 high. The notch is 24mm X 28 high.

I always presumed it's a play on the word pioneer. Plioneer saying 'play - on - here'. If that makes sense

Just checked - cherries on three of mine; one has the cherry same as yours, the other's normal.
Picture of cashbox:

I have one of these which was in storage for at least sixty years and, I believe, all original apart from the motor. The top pediment is a bit different.

Here's the picture of the center and it works well, like playing a bingolette
