Great buy, and indeed I won't fit in it. Someone offered me a drive in his Austin Tilly, but I could not manage to fit behind the wheels and use the controls safely. Another dream smashed. Oh well, I'll have one of them MW's
Re. the Motley mount, they are extremely rare. A gentleman over on MLU found one in the States I think to fit in the back of his 15-cwt CMP.
To be honest, I think they look silly, especially in the back of a Tilly which should in reality be used only to ferry back and forth nurses to an army camp and the pub!
