Well Byron, about the only info i can come up with is that its a 1949 crossley.
You're close enough Jon ............
To satisfy it's post-war traffic requirements, Western Welsh would have ideally liked more Leyland Tigers, but due to production difficulties and overwhelming demands at Leyland Motors, it turned to Manchester-based Crossley Motors.
Accordingly, 38 Willowbrook-bodied Crossley SD42/7's arrived towards the end of 1949, and were given fleet numbers 902-939 (DKG 902 etc).
Here's 938, awaiting delivery from Willowbrooks' works at Loughborough in Autumn 1949.
Though robustly constructed, they soon attained a tarnished reputation at WW.
Crossley's own straight-six diesel lump suffered badly with crankshaft/bearing issues, whilst their handling characteristics in inclement weather conditions meant that many were de-licenced during each Winter period. A goodly number spent their lives based at Bridgend, and tended to be used on the lightly-trafficked rural routes in the Vale of Glamorgan area.
Little wonder then, that Western Welsh returned to Leyland as it's preferred chassis supplier!
All the Crossleys were withdrawn and disposed-of by 1962, whence a goodly number of these leviathons arrived:
............... anyone?
