Yes sorry it was an “in joke”. The Fin Fuel Tank did not have a gauge. All it had was a light in the cockpit that indicated:
“Fin E” – The Fin was empty
“Fin” – to indicate fuel was transferring
and
“Fin F” – The fin was full
You always watched for this light when refuelling. Therefore when you got totally hammered at a beer call you had achieved “Fin F”
AGS man,
We had a few beeps going off in the ASF Hangar as well
