Didn’t even know late model is exists for Mk 108.

Which aircraft was it mounted on?

22

Beyond some test aircraft it did not see service.

23

Mostly they used it for Me 262s or Fw 190Ds?

24

Most likely also mounted on Bf 110s, they often used that for testing, like the Mg 213C.

A few notes on the 7.9mm ammunition:

  • There was no “smk l’spur -v” only “smk l’spur 100/600 -v”. The Luftwaffe had already switched from “smk l’spur” to “smk l’spur 100/600” prior. (Tracer is visible after ~100m and burns up to ~600m range.)
  • The “-v” ammunition was introduced in the 2nd half of 1942, therefore the “ordinary” should still be relevant for early aircraft.
  • At the beginning of WW2, there was also an incendiary round in use. Production ceased 1940. “7,9mm Pr” or sometimes S-Pr. It was more or less, the same round from WW1. (More Info can be found in Waffen Revue No. 5)
  • Even though the “-v” ammunition could be used in the MG 15 and MG 81, it was neither recommended in 03/1943 or 06.1944 for their belts. It was only recommended for “Jäger” (compare L.Dv. 4000-10). It also says: “z. Zt. nur für starre Fliegerbordwaffen MG. 17” (At this time only for fixed mounted aircraft mg 17)
  • Another missing round is the “7,9mm PmK n.A.”. It seems that this one has no tin-sealed opening and also has phosphorus in the tip above the penetrator.

Other missing 7.9mm cartridges:

  • 7,9 mm s.S. (fmj ball)
  • 7,9 mm S.m.E. (ball with iron penetrator) replaced “s.S.” and was the standard bullet in slightly different variants (~1940)
  • 7,9 mm “S.m.E. L’spur 100/600” (tracer with iron penetrator) replaced the “S.m.K. L’spur 100/600” for the Luftwaffe. (~mid 1944)

Yeah but from what I can tell it also has less in the middle.
So overall still the same amount.

27

That’s true, but the old round was already burning up parts of their filling flying towards the target, leaving a rotating smoke tracer. The “n.A.” should ignite only on impact.

Well, i added the P.m.K. n.A., tho idk on the filling, only 1 picture. Added the normal velocitys in the Spoilers.
Didnt add the Ball nor Sap ammo, i think its a bit redundant here. (Or rather maybe i cant be bothered, but if you write it in a comment, i might C&P it in.)
