The Half-track M3 has been issued in September 1960 and made in Bobigny until the factory closed in 1971.
1960 - 63 • Base plate and tow hook painted black, no machine gun.
1963 - 71 • Bruno finish base plate, army green tow hook, cal. 50 machine gun, stregnthened rear mud guards. As above.
1970 • Dichromated base plate, army green tow hook, cal. 50 machine gun, plastic rollers, stregnthened rear mud guards.
Shown on page 13 of the 1960 French Dinky Toys catalogue with ridged hubs, this model has only been made with concave hubs.
There has been as discussion about the washers / spacers fitted to the 27d Land Rover and the 153a Jeep. The late issue half-tracks have also been fitted with such spacers.
There are two types of tracks, one with 60 ridges and the other with 70.
I do not know any other Dinky Toys with a golden base plate.
