Blackburn bought several batches of both double and single deck buses with Crossley bodywork in the late 1940s. 7, BCB340, is a Leyland Tiger PS1 with 34 seat rear entrance body.
At some point in its Blackburn career it was partially rebuilt losing the characteristic Crossley stepped waistrail in the process. In preservation for a number of years the bus was last heard of with Silver Star of Caernafon in 2008.
