[Premium-Rx] Stoddart Receiving Loops

[DOXEMF at aol.com]

Hello,
My first posting here is a question.
Would anyone happen to know what Stoddart Loop matches the remote head 431-1A? Pix here:

This looks like it would be a real nice H.F. loop but have had no luck finding just which receiving set this was part of.
A manual might give the construction and preamp details.

Thanks,
BIll
