Atkinson of Clitheroe gritter body

[Tar-Pot]

A freind is looking for a gritter body made by Atkinson of Clitheroe (the type used for gritting the roads in winter) to mount on the back of an old lorry. Something made in the 1960's would be preferable although anything in any condition would be considered. Any information would be greatfully received. Many thanks. Jeremy.
