Dual Purpose Mk1 (DP1)


The DP1 was developed to replace the wartime and early post war Water Tankers as Water Backups to the Foam Tenders. It was supplied by Foamite on a Thornycroft Nubian 4 x 4 chassis with the bodywork built by Tecalemit. It went into service in 1957 and was supplied until 1958. These continued in service until 1980.

As the name suggests (Dual Purpose) it was used not just as a water carrier but could be used as a Foam Crash Truck and was also equipped for Domestic Fire Fighting. All operations where made from the pump locker at the rear of the vehicle

This vehicle 24 AG 59 saw service at RAF Gaydon and RAF Topcliffe. It left RAF service in 1974 and was obtained by the Potter Group at Rippon and re-registered as KFF 132.In 1993 it was bought by the Thornycroft Society and restored. It was acquired by Steve Shirley after seeing it advertised for sale on ebay, Steve is really grateful to the Society for selling it to him.
