Thank you for replying Norm. I live not too far from Kingswood so will try to find out if the post exchange is still there. Not just at the moment though as I have a bad back which is preventing me from doing much!
There is still a pub called the Cock in Sutton which is probably the one you went to.
Do you remember a building in Sutton itself where Canadians apparently reported before being assigned their units? If so, do you remember where it was?
Regards, Mary
