Thanks for your posting Coddy, Williams Bros’s yard in Queensferry was on the old A548 (as it was then) going towards the blue bridge on the right hand side just after the railway bridge - Flintshire Caravans now occupy the yard and offices. They had a fleet of Bedford TK’s and Atki’s when I remember them in the 60’s and later Scania 110’s and 111’s. I think they were still there in the mid- 70’s although I’m not sure when they closed the Queensferry yard.
I can remember them in Alltami (nr Buckley) later.
Cheers - RR
