Ref “portable dark rooms”. A clutch of ATRELs ( Air Transportable Reconnaissance Exploitation Laboratories) is hopefully going to be set up with the IWM at Duxford.
A number of ATREL’s have been moved to IWM Duxford, they were the one’s used by 41(F) Sqn.
At this very time I’m working in an ATREL in the desert, I’m on detachment with 39(1PRU) Sqn, we have a set-up of 5 cabins.
I have posted pictures of the PR9 canberra at the following link:
