Over the years, Budgie produced three Euclid models based on the famous earth-moving vehicles and in fact two further Euclid models were planned, a Crawler Tractor and a Bulldozer. As it turned out, however, the Euclid Mammoth was the last but it was certainly the grandest.
For the cab and chassis of No.318 Euclid Mammoth Truck, Budgie took the opportunity to re-cycle the castings from the earlier Euclid Tipper Truck No.242 but with a fresh colour scheme, an additional set of wheels and a different coupling system. The cab had a bright new appearance with green paint, silver trim on headlights and bumper, and unpainted metal cylinder but unlike other late Budgie models no windows were fitted.
The yellow chassis of the original Euclid Tipper Truck also had some alterations. A strengthener for the extra set of wheels was added where the old hydraulic rams had been and a new coupling system was installed at the back.
The trailer of No.318 Euclid Mammoth which carried the huge dumper was coloured yellow like the chassis and incorporated twin hydraulic lifting rams. These were unpainted as was the little clamp which rivetted the rams to the dumper. Underneath, two blocks of lettering were cast, 'Budgie Models No.318' at the rear on a little panel and, at the coupling end almost hidden, was 'End Dump Semi-Trailer'. Interestingly, under the cab and chassis the words 'Budgie Toys' was cast so the Euclid Mammoth carried ID from both the early Morris & Stone era ('Budgie Toys') and the later years under Guiterman ownership ('Budgie Models').
Dominating the appearance of the Euclid Mammoth was the long orange dumper. It was hinged at the rear with a crimped retaining pin and so when raised it lifted up high above the trailer. It could carry a large load and as if to emphasize this Budgie had 'Truck Capacity 80 Cu.Yds.' cast on the underside. Also underneath at the front was cast (and mis-spelt) 'Euclid Mamouth'.
In all the Euclid Mammoth had 18 wheels. These were unpainted ridged metal wheels fitted with heavy treaded tyres not used on any other model except the earlier Euclid Tipper Truck.
The first issue of No.318 was in the standard yellow 'Budgie Models Ltd' box (B4) but this had a very short run before being replaced by the later blue & white open-sided window pack (C2).
The Euclid Mammoth Truck was probably quite popular despite being an expensive toy because it is not too hard to find. Boxes however are very rare and the B4 yellow box is one of the rarest of all Budgie boxes.
