Ambulance
412 Bedford CA Ambulance
November 1957 - 1960 (Mk I)
January 1960 - 1960 (assumed) (Mk ii)
Revised sometime in 1960 to MkII single screen form.
The Mk II edition may have been issued with shaped wheels but I am not aware of any. The MK II edition is scarce anyway so one with shaped wheels would be quite a find.
437 Superior Ambulance on Cadillac Chassis
October 1962 - 1966 in red and white.
July 1966 - 1968 with a new battery unit and mechanism and in a new blue and cream colour scheme.
Available with clear or amber small lights. There is a slight difference in the design of the amber warning lights too.
The first version had a light that flashed by contact changing at the rear axle, similar to the first 464 Commer Police van. The second had a different arrangement whereby the bulb itself flashed and there was no connection with movement of the vehicle. The early edition had fixed shaped wheels (required for the correct operation at the back anyway) whereas the second version had free-spinning shaped or cast wheels. Cast wheels seem to be more common.
463 Commer Ambulance
February 1964 - 1966
A similar model could be created in the Commer Construction Gift Set 24 issued in 1963 but this boxed edition has a fixed base and is easily identifiable in that respect.
482 Range Rover Ambulance
May 1975 - 1977
Another variation of the Range Rove, this time with difference roof furniture and a black 'Ambulance' stripe and label, as well as red cross labels.
This came in the box with twp ambulance men carrying a patient on a stretcher. I am not sure whether this actually fitted inside the model, however!
The wheels are the 'four crown' type but may have been revised later as this model was in production when later types were more common.
