[Boatanchors] Johnson Matchbox in Hints and Kinks?

[Robert Goff]

I'm looking for an article on the use of external coils to extend the
range of the Johnson Matchbox to cover 160 meters.  I believe it shows
up in Hints and Kinks for Dec. 1963, but, unfortunately, my QSTs don't
go back quite that far.

Anyone have a copy or scan of the article they can send me? I would be
much obliged.

Thanks,
Robert
