The bike on the right seems to have a "Maltese Cross" as a blackout mask? And the one on the left a "Shell" badge, could it be cut out of a petrol can?

i've seen a 2 gallon petrol can with that type of cross once but i don't remember which brand was it. if i am not mistaken Valor was one of the main makers who did sum contractiong for many of the feul suppliers like Pratts, Shell etc

sorry rob but its 2 holes in 2

Above the shell, there appears to be stamped letters, I can make out a T and an R, not letters used in Shell?

Ik bedoelde dus in een keer goed, nou jij weer, wijsneus!

There seem to be lots of varieties of 2 gallon can, some say "Motor Spirit" or "Aviation Spirit", it could be something like this?
