My dad was fleet engineer at Smedley’s Foods in Faversham,and as a youngster I remember they had a fleet of them,including some bonneted normal control Trader’s.
They had box bodies with roller shutter sides for canned deliveries and fridge bodies for frozen.
He used to bring one home sometimes when he came home for lunch,and whilst he was eating,I’d be sitting in the lorry doing all the brrmm,brrmm business (as you do).
They were eventually replaced by D’series Ford’s.
Now,if anyone can find some pics of the old Smedley’s motors…
