What an interesting find. Thank you 'dcrfan' for the posting. The lower picture of the Bedford truck with trailer has the identity of CFMU 2 on the door. As our
Maps Page illustrates, this unit was originally formed in Chatham during May 1944. After D day, as the European War progressed , it spent some time in Copenhagen finally ending up in Wilhemshaven. At one time, this particular unit had Lt Cdr Bradford, of 55th 'Dog Boat' Flotilla fame, as its CO.
There is still much to know of these valuable units; many were formed in the Mediterranean and Far East. Further information and any images of these and their working would be most welcome.
