Unkown 75 mm Rheinmetall shell

[greif]

Does anyone know what 75 mm gun this Rheinmetall shell is made for? Because the width of the driving band is only 7 mm I think it must be for a low velocity gun, like an infantry support gun or a mountain gun. Perhaps it is an export gun. The gain of the inert fuze contains a wooden piece and the fuze has no markings. My guess is that it is a display model.
Thanks,

Bump this thread.
Something new ?

This shell is in the collection of Burney Davis now.
I think I found a sectioned model of this shell on the website of the Swedisch DigitaltMuseum, but it doesn’t make me any wiser about the gun and the country it was made for.

Mentionned as German Rheinmetall, no other details.
The fuze is shown and a brother one piece filled black powder.
