You are right - Jim Coleman was the designer . most ingenious device and
easy to make one.

And indeed "anybody can make his own, not "its" own, I guess the meaning is
different (?)

Well, make that twice I replied to Isaac instead of the list:

  I recall an ingenious device from Sanderson, that anybody can make its
own, these are 2 rules (of different height) made of strips of thick paper
where the spacing at the end of the key is marked with the partial series
enlighten. The 2 strips can be used one at the lower note of the interval to
be tested and the other on the highest, and the scale show immediately where
the partials are coincident.
Just last week I made such a device (in minutes, out of poster board) for my
PTG chapter tuning demonstration. I think everyone should have one until
they are facile with the partial series and coincident partials. I gave
credit to Jim Coleman, Sr., because that's who my fuzzy memory contained as
the first person I saw use it. Was Al Sanderson actually the first? It's so
clever I would like to credit the right person.
