The Bristol L with ECW body was favoured by Tilling's Group during the late 1940's and 50's, the same body was also fitted to the Leyland Tiger PS1 chassis and this was also operated by some of Tilling companies as well as a variety of operators outside the group.

This casting is also the basis for the Bristol L ECW bus (405).
Only six releases have been made since 1995 with the last appearing back in February 2001.
