From Graces Guide
Note: This is a sub-section of Scammell.
The Handyman initially used a glass fibre cab designed by Scammell - for the Mark 2 and 3 versions a new Michellotti-designed "cheesegrater" fibreglass cab as used on the 2nd and 3rd versions of the Routeman Rigid was fitted.
Early versions were equipped with Scammell's own "gate-change" gearbox but subsequent versions were fitted with AEC and David Brown gearboxes.
Engines fitted included the Leyland 680, Gardner 150 and Rolls Royce 220.
