French Dealer box?

The 9.3x72R ammunition box shown below was from a French Auction site. It contained new Czech "PS * 9.3x72R * " headstamped ammo.

Does anyone know who the Paris Dealer (?) was that is shown at the bottom of the label:

It looks like “Marcel or Marius Leposte” but I have had no luck with that or the “no-Zust” (Rustfree ?).

Anyone ?

I read that as “Marque Deposée”, means registered Trademark…so no Dealers Name,but no-rust
…and PS is Long gone …
Will check some friends in France…

That makes sense Peter.

Thanks for your help.
