Folks,

I have a few 75mm M18 shell cases which I've picked up over the years from Normandy and a couple of them are marked with the word 'SUPER' in black lettering on the side of the casing and almost transparently marked the same on the base.

Can someone enlighten me to their meaning 8)

Cheers Dave

M18 = 75mm Gun - eg Sherman
M5A1 = 75mm Howitzer - eg Pack Howitzer M1A1, M2, M3 etc

SUPER relates to the shell filling... eg, from Wiki...

The primary round was the M48 High Explosive. This 6.76 kg (14.9 lb) round travelled at 625 m/s (2,050 ft/s) and contained 1.5 pounds of TNT filling and choice of SUPER Quick (SQ) or Delay (PD) with 0.05 or 0.15 seconds of delay fuse. SQ was the standard setting with PD used against structures, gun positions or lightly protected vehicles.

http://en.wikipedia.org/wiki/75_mm_Gun_M2/M3/M6

Hope this helps.

Tim

Super relates to a larger charge of propellant for the M48 HE round. It is nothing to do with the projectile itself. Super quick is a fuze setting.
