Notes:
I have only searched a subset of the Norfolk city directories¹, so the addresses & dates listed above are incomplete. It seems there were 2 stores from 1934 to sometime between 1940 & 1949.
I don't know if "Master's Drug Store" was related to "Master's Pharmacy", but I listed the data for it above just in case.

(more information will be added when I get around to researching this druggist)
