Just to throw some more confusion into the fray, in the 1937 April-May
issue of National Radio News, a magazine published by National Radio
Institute, a subscriber writes, "I am sending you a station card from
amateur station W21OR, owned by graduate King J. Fothergill. It will be
a pleasure to see my call letters appear in the ever-growing list of
N.R.I. Ham stations".
Was this a misprint? Should it have been W2IOR? He was from NY.
Inquiring minds want to know.

It's a misprint. Fothergill was W2IOR in Bellerose NY.
