A Guy Big J4T and a fascinating series of photographs depicting the loading of an drawbar trailer mounted Mobile Telephone Exchange. (These mobile exchanges were used to supplement existing exchanges). The rear axle of the trailer is removed to enable the exchange trailer to be hand winched onto the trailer bed.

The registration numbers chalked on the rear of the Taskers Mobile Exchange were allocated to Maudslay 6 wheel trucks, which may have been used to tow the trailers on the road originally. No doubt the GPO felt it safer to move the mobile exchanges on the back of a semi-trailer than have them towed.
