I won’t say how old I am but back in the late forties and early fifties we would carry the following:
A loaded grease gun
Two cans of Mil G 7711 grease
A mechanics tool pack to include a roll of safety wire
A couple of cans of oil. If flying in a Bell 47 a can of fish oil for the tail rotor gear box
A mechanic
A RON bag with two days supplies.
If flying in the Arctic two fully fitted survival packs to include a 222 Armalite rifle with ammunition and Arctic sunglasses.
