I have looked up the years 1962, 1963, 1964, 1965, 1967/68, 1969/70. I have looked under street listings and found nothing so I looked under names listing and the only Stockton to be found is at 8 Greenway Street. I did find another Stockton listed at Dollman Street the one year but they were press workers.
Roy as I said there were many dining rooms and cafes on Cattell Rd and one chippy and I checked both sides of the road from Coventry Rd up to Bordesley Green but nothing in the name of Stockton and no bakers or pie shop.
