[Milsurplus] Crystal Drive Unit for RAF T1154 Transmitter?

[Roger Basford]

Hi All,

Had an AM QSO on 80m with another G who was using a T1154 transmitter, the 
standard fit in aircraft of RAF Bomber Command of WWII. He is seeking some 
info on "Crystal Drive Unit Y10D/500, 550" which is of Australian 
manufacture (post WWII) and can carry up to 12 crystals. He has the circuit 
diagram and what appears to be one page of the technical instructions but 
would like to have a photo of the device to replicate it. The technical note 
is headed "Australian Addendum No 1 to Chapter 1 of AP.2548A" and is dated 
Feb 1954.

Of course, if someone has such a device lurking in their junk 
box........................!

Any info appreciated, I know we have quite a few VKs on the group.

73,

Roger Basford/G3VKM
