Question about an unknown bullet type in 9mm Luger

This loaded round with that shown bullet, was found loaded into an old (early) MEN Brass case. But this load is NOT from MEN, as they stated to me. They never made such bullets.
Does anybody here knew the manufacturer of this bullets (or the loaded ammo under use of foreign cases?)

Thanks for your help…
