Elliott,

Hi I was wondering if the Whitley rebuild has one of these?

"You are bidding for an early bomb jettison unit fitted in the bomb
aimers position on Wellingtons, Whitleys and Hampdens. This bakelite
unit has a flip up brass lid to press a bulb to emergency jettison
the full bomb load. It was recovered from the crash site by an estate
manager in the seventies.The Wellington was aircraft W5613 of 21 OTU
which crashed at Orchardleigh in somerset 4/1/43.This unit is not too
far gone to be fully restored for display on a bomb aimers panel,
very hard to find these. Unit number is 5D 604."
