Carrier Fuel Dipstick

[Pedr]

Hi Folks

A Mate has this in his collection.

Obviously it is a carrier fuel dipstick, but we were wondering exactly which models it is for - are they all early model British / Canadian carriers.

The internal section is made from red leather. It's untreated so the fuel wets the leather indication fuel depth. Great when taking the first measure, but what happens when the second tank is lower than the first? ( I believe there is only one stick per carrier )
