Jif, the head honcho

Racking my feeble brain cells, I seem to recall that this might have derived from RAF ground crews who used this sign indicating that they needed assistance to bring a starter mechanism to fire up an aircraft, and at the same time saying :Two six on the trolley acc". (Trolley accumulator).

Jon,

Can't answer the two finger salute, but "Two Six", now according to a WW2 book on RAF slang;
TWO-SIX (as a command) Push! (As a verb) Hurry! Thus, "Two-six on the hanger doors!" or "If I don't two-six I'll be late". Originated from the procedure when pushing aircraft by man power of having two airmen on the tail to guide and three on each mainplane.
