The vehicle was designed to carry a complete set of tools and equipment for the repair and maintenance of telephone lines and installations and was equipped with winch and derrick poles. The vehicle was operated by a trained telephone line construction crew of Signals' personnel. The 4-K-1 body was of all steel construction and consisted of a steel platform with specially constructed bins and lockers which were designed so as to form the sides and front of the body. The top was of 3 sections, telescopic design, the fore and aft sections being of steel while the centre section was of rubberized canvas. Tools and equipment were stowed in designated positions over the body while specialty stores were stowed in the individual bins."

The vehicle code for the Telephone Lorry was 60444-M-SLC-1. SLC=Signal Line Construction?
It is also stated that the vehicle had a crew of 5, 10,000 pound winch (which could also power a detachable cable reel that mounted to the round shaft seen in the open locker at the right front of the body). The derrick is not the same as used on the derrick lorry. The telephone lorry's derrick had 2 brace legs which attached part way up the central leg that could be extended well past the attachment point of the braces. It is possible that the angle of the main pole could be adjusted by moving the attachment point of the braces, but this is not certain. By contrast the Derrick lorry had all 3 legs coming to a common point at the head sheave with all 3 legs adjustable for length.
