You have assumed correct. Have a look on the next page, the back cover of the leaflet usually mention the ammo types in use:Yoozername wrote:This is from the German document from Feb 1943 regarding the 7,5 cm KWK L24. I would assume that it is HL/B...HL is HEAT and SP is HE.
Pz = 7.5 cm Pzrg Patr KwK
Hl = 7.5 cm Gr Patr 38 Hl/A KwK and 7.5 cm Gr Patr 38 Hl/B KwK
Sp = eingeführte Sprgr Patr
And they note: "For HL Granades no ranges are given, as under normal circumstances, any black marked areas could be penetrated up to 1500m, but in combat, a potential hit at range would be many times lesser, since visibility and the distraction due to enemy action would considerably decrease the probability."
