Tilly was the name given to British Small Staff Cars coming from the word "Utility". These Tilly vehicles were produced in large numbers for British and Allied forces during WWII from civilian car designs. They were severely underpowered, but served with distinction and stayed in production throughout WWII and could be seen on every front. This British Staff Car was powered by a four cylinder 22-kW engine derived from a 10 HP commercial saloon.
