When the British decided to use the 7.92x57mm German cartridge in the BESA tank machine gun, they knew that capture German 7.92x57mm could be used in the BESA - my photo shows German WW2 7.92x57mm cartridges in the BESA belt

The headstamps on the German 7.92x57mm cartridges in the BESA belt are:

first; 3 41 emp S* black band at bullet seat

second cartridge is the same

third: 12 37 P S* red band at bullet seat

fourth; 1 40 P25 S* red band at bullet seat

I do not collect 7.92mm German WW2 but could find out these codes

However the Britis had to check with an armourer to know if they could use captured german ammo in the same gun

On my photo of the BRESA tank machine gun links with German 7.9mm cartridges, you stated that you did not know of any 7.9mm ammo that used case mouth markings like that !

I was able to identify these 7.9mm German cartridges they are as follows:

S.m.k. Tropical pointed bullet steel core two red bands.

S.m.K. L. Tropical steel core tracer black tip with two red bands

S.m.K. GI Spur Tropical night tracer small black tip two red bands

The case mouth colors were the sealant to protect the cartridge in the
tropical climate such as Noth Africa
