Interesting. I've found a "Modification XXX depth charge" link:
You won?t believe this one weird trick they used to fly beer to the D-Day troops in Normandy | Zythophile
which is a good read. According to the article, the drop-tank in our picture is not the Mod XXX, but is a Typhoon/Hurricane jettison tank modified to carry beer on the Spitfire. The Mod XXX was a carrier to enable actual barrels to be carried - one under each wing!
