I forget to mention that the article is in the edition of the handbook
copyrighted in 1962.
I hope that helps.

A detailed construction article about to build a W9TO keyer may be
found in Bill Orr's "West Coast" handbook on pages 597 - 600. The unit
in the handbook seems to have a circuit that is identical to the T.O.
keyers commercially manufactured by Hallicrafters.

Don -
According to an Editor's note in the article, "Transistorized
Electronic Key and Monitor" in May 1959 QST, a semi-conductor version
of the 9TO keyer, the 9TO Keyer "... has not been described in any
periodical, but has been furnished privately by W9TO to a number of
amateurs."
Interesting side note... The keyer in the article used CK722
transistors!

I have a piece of homebrew here that says in Dymo labeling that it is
a "TO Keyer". I'd like to look this up. Does anyone happen to know
the ballpark year when the original TO Keyer article was published?
In QST I assume?
