International Prototypes

Prototypes were constructed for the No.1 Mk.1 and No.1 F1 and F2 6x6 vehicles. Details and images of these photos appear below.

Some information on this page, as well as further information, can be found in Mike Cecil's Article, Remember when ... we built international trucks?

Information on the XF4 prototype vehicles can be found on the XF4 1 Ton Truck page.

International No.1 Prototypes

International built 3 Prototypes for the No.1, Mk.1. If you have any more images or information about any of these vehicles please contact REMLR.

P1 and P2 shown below would appear to be prototypes of the Mk.1 fitted with different trays and cabs. It is thought that the initial cab was simply a modified ome from a WW2 Blitz truck, and then later a cab closer to the production one was fitted.

We do have a single photo of P3 from "Forty Years of Army Design".

This vehicle appears to be Prototype 1 and has a much deeper tray than the production Mk.1

Another vehicle, this time Prototype 2. The windscreen appears to be a later model and somewhat nearer to the production version, as is the tray.

Further Mk.1 Prototypes

As early as 1958 International built a prototype 6x6 Mk.1 as can be seen below on the left.

This appears to be one of the two Mk.1 6x6 prototypes that were built in 1958.

International 6x6 Pre Production Vehicles

A1 and A2 along with B1 and B2 are pre production 6x6 vehicles. Unusual features include dual 10.00x20 rear wheels on the Tippers (B1 and B2) and a slightly different tray configuration on the GS vehicles and single 12.00.20 tyres (A1 and A2).

A2 would be a sister vehicle to A1 and would have been trialled at Monegeeta on their extensive test circuit whilst A1 was at Innisfail and Cowley Beach.

This photo is one of the Mk.5 prototypes with a different fuel tank configuration to the original and sporting a Mk.3 cab. Also note the buldge in the bonnet for???

This vehicle resides at the Army Museum Bandiana.
