That's
not a Crusader cup,
That's an
85 pattern mug you have there mate!
made a decade before the crusader cup canteen!
Nice one!
(the give away sign is the ribbing or folds in the metal down the sides, something to do with the manufacturing process)
Survival Aids used to sell them back in the late 80's.
designed to fit on top of your 58" bottle
upside down (instead of the 58" plastic cup)
I don't think they were an issued item, i think the army went straight from 44" cups to crusader cups.
My local surplus shop still sells them for £20+, Why are they more expensive?
I never figured out why.
Do you have the plastic rim that came with it? in the bad old days of soldiering, squaddies would place a piece of electric tape on the rim to stop lips getting scolded on the hot metal, the 85 pattern mug had a removable black plastic rim, apparently the seal when in use wasn't great and hot tea would dribble through the gap.
the lip of course easy to loose and break or melt too!
plastic lip sort of fantastic idea on paper, but not so in practice.
