Dialled Despatches
Dialled Despatches, manufacturer of pneumatic tube systems, of Gosport
By the early 1970s, C. and N. Electrical had grown to employ 1,250 people in five factories and had, in its turn, spun off further developments such as Dialled Despatches which manufactured pneumatic tube systems[1] in which carriers could be routed to the correct destination, at first using the note produced by a reed on the carrier to operate switches, and later using a series of metal rings on the carrier to make electrical contacts in the tube. The company was based in Gosport, Hants.
1976 Dialled Despatches took over Lamson Engineering Co and renamed it D. D. Lamson.
1980 Successful year for D. D. Lamson, document conveying subsidiary of Crest Nicholson[2].
1987 Frederick Cooper plc acquired D. D. Lamson from Crest Nicholson
