The Mobile Excavator was a combination of previous models to create a toy with good play value but which as a real vehicle would probably not have been viable!
The casting of the cab and chassis were indentical to the AEC Sunderland truck which Benbros had used for several former models but a small strengthening panel was added above the rear axle presumably to cope with the weight of the excavator body. It was painted red and the metal wheels were usually yellow although later replaced by coloured plastic ones. The black tyres were lightly treaded. Under the chassis 'Benbros Qualitoy' and 'Made in England' were cast.
Like the Mobile Crane, the red & yellow Excavator body was centrally fixed to a platform on the chassis held in place by a tab behind the cab and a rivet at the rear. Benbros used the second type Excavator with unpainted metal handles and a pin securing the arm and bucket to the body. '10-RB' decals were added to both sides and 'Ruston Bucyrus' was cast at the back.
As with the earlier Excavator the lifting arms and bucket were painted green.
The Mobile Excavator shared a yellow & red box with the Mobile Crane with illustrations on opposite sides and model name in a large panel. On one end-flap a blank panel was left for the model details to be added, in this case 'M Excavator'.
This is not a scarce model in playworn condition but mint, boxed examples are much harder to find.
