Portugese 7.65 Parabellum box

I believe this box is labeled for a ‘machine pistol carbine M1930’. My Google search turned up a Portugese M1929 machine pistol. Would I be correct in assuming these are the same gun? Also, I am having trouble reading the maker’s name. What headstamp would be expected on the cartridges?

Guy - although the cartridges were made by F

Thanks, John. Very informative as usual.
