Thanks for the info.
I've currently got a home-made GS Style body on the back, something else to consider is that the QLB chassis is shorter than the standard one, and in my case even shorter still.
Looking through Bedford to Berlin it seems 1942 was a scarce year for QLBs, compared to the other years of production. I wonder if Vauxhall still hold any records or drawings......
I tried to trace the WD number at Beverley, but they didn't have anything at the time, all I have is the chassis number; QLB12686.
It's nice to have the original, pre-hip ring, cab roof, and also be only the 4th owner since it's relase from service too.
