Box markings
Hi Sebastien,
I can assist with the interpretation of some of the markings, if this would help.
Image 1:
XXX in red indicates the ammunition is suitable for use in hot climates, so essentially all climatic conditions.
3.7 is the gun calibre, ie the 3.7 inch Heavy Anti-aircraft gun.
B843A is the ammunition batch number and sub-batch ID letter.
TNT indicates the explosive type inside the projectile
Image 2: the yellow markings are WW2, the white markings are post-war overwriting. Note the 'AA HE' has been blanked out in white. See image 3 below for the reason.
The 'L' in a square indicates the propellant is Flashless Non-hygroscopic nitro-cellulose powder usually abbreviated to FNH or FNH/P.
Other markings as per image 1.
Image 3: the yellow stripe indicates the ammunition within the box has been converted for practice purposes.
FCC is the Fuze Factor Correction.
Image 5: yellow stripe = ammunition converted for practice purposes
Image 8: The rounds were examined by an ammunition technician for any defects in April 1950.
Image 9: 'Converted 6/51'
Image 10: as per Tony's comments regarding the explosive label.
Hope that helps. A fine example of an ammunition container with plenty of verifiable markings.
Mike
