Check out The Elizabethan Home: Discovered in Two Dialogues by Claudius Hollyband and Peter Erondell, Ed. Muriel St. Claire Byrne. London: Cobden-Sanderson 1930.
Muriel St. Claire Byrne was a close friend of Dorothy Sayers' and partnered with her on a number of literary projects, including the stage play "Busman's Honeymoon", which Sayers subsequently expanded into a full-length novel. It is not so surprising that something Ms. Byrne edited and published in 1930 should find its way into a book that Ms. Sayers was writing in 1933-34.
I haven't been able to purchase a copy of The Elizabethan Home yet, but it is available in a few libraries.
