To clarify, a ‘confectioners’ would have been a shop selling sweets (a candy store), rather than a bakery. The buildings on Olivet Road look to have been extended substantially in the photo attached, which was in 1966, if the different coloured pointing is anything to go by? At this time it was a place of worship.

Also, a photo of the Sheaf Market (Rag-and-Tag) from the 1920’s, which is of the period you were looking for, but sadly no clue as to which is stall #11?

Hopefully they will give a sense of the period and the surroundings?
