::::I've been looking into this more today. The above mention of "Allen" is actually the reference that is given in List of stars in Cepheus:  near the end. There it says, "υ1 and υ2, 5th‑magnitude stars, are given by Bayer, under the title Castula, as from Nonius, equivalent to Ταινία, the Front of the Garment, which they mark." Unless I missed something, Bayer gives none of that information (see  image 19 [p. Dr]). My investigation may continue...
