Not much help I’m afraid. What I have for 11 Booth St is:
1921 Barrows, Francis James
1932-3 Newbold Frank
1936 11 Currall, Lewis & Martin Ltd. Constructional engnrs
1936 11 Leach Fredk. H. A.C.A.chartrd. accntnt
The electoral roll shows Frank Newbold there in 1930, but it is someone different in 1927, and no-one is listed there in 1935 (the “no-0ne is determined by looking in the actual roll, not just from the results of a search)
Cannot find Handsworth Garden Bakery listed in any of those years in Kellys.
