The inscription listed below is on a shell case which was in my grandmothers house. Can any one tell me what they mean.


QF. 18.PR






Picture of a highly polished shell case; letters are barely visible at the bottom

It's a shell for the standard British Ordnance QF 18-pounder field gun.

Shell markings will normally include the following:

  • Calibre and numeral.
  • Manufacturers “ initial ” or “ Trade Mark.”
  • Date of completion of manufacture,
  • C.S. or F.S. denoting whether the casing is made from Cast or Forged Steel

In this case, we have

  • QF 18 PF meaning it's a Quick Fire 18-pounder
  • VII means it's a mark VII shell
  • FS means the shell casing is made from forged steel.
  • 9.11.15 is the manufacture date

I'd guess that BRC is the manufacturer of the shell casing, and (TR over MH) is the monogram of the filling station.

A lot of filling stations were established during the first world war. There is a list of initials used by filling stations in 1918 in Explanatory List of Service Markings to be found on ammunition and ammunition packages in use with the Field Armies. 1918. Sadly, it doesn't include the markings on your shell casing. Unfortunately, I couldn't find an earlier edition online.

The 1915 treatise on Ammunition from the War Office also has more detail about the 18-pounder ammunition.

    Thank you. That’s very helpful. My grandmother worked in the Hereford Munitions factory during WW1. Oct 30, 2017 at 14:25
