Thanks, but I guess I should have been more specific, I'm looking for online sources for the catalogs - libraries aren't an option and can't really fly to England to consult a college's collection. (If they offer the catalogs online, I can't figure out how to access it)
Harrods did have a catalog (or catalogue) and you can get a partial reprint of the 1929 one, but it's a little expensive and about 5 years later than what I'm after.
To answer my question, they sort of let you look at the old Kays Catalogs at
But it's by separate images, not the catalog in a PDF and the images are too tiny for me to read.
