Thank you very much I have a new investigative tool now…I think this atkinson was built around 1955 it still has the wooden cab …and for some reason not registered in the uk until 1959.
i found out from that site that the Matchless motorcycle i have just bought was last taxed in 1979! 
back to the Atki…John Ellis & Sons were bought out by one of my old employers,Redland,and their old works at Barrow still had the name on one of the buildings…may still have! must have a snoop around one day
