Having been donated a homebrew "L" antenna tuner, with
an unidentified roller coaster (about 1 1/4" in diameter, with
a plastic facia turns counter marked "antenna loading" with the
plastic facia looking like a CRT's barrel distortion, any ideas
as to its origin, anyone?)
if it has a black plastic face it sounds like the one from old Collins TCS
12 u.s.navy tx. got one here also! also brought back waves of
nostalgia from the days of REAL hammery!

Doug, brilliant...in response to your heads up, a quick google brought
up numerous pictures to confirm it.

Thank-you...arigato gozaimus!

The next question for all is....how to clean up the green verdigris that is
on some parts of the coil, and also the brass pulley that runs up
and down the coil.....ie...how to clean it but without doing damage
for the future. (And I suppose that means that taking that exercise with
yesterday's antenna exercise that in the space of 24 hours I will
have done everything that Mrs.Nugatory has ever done, plus
all the other experiments (including some mistakes about
which I'm not the least embarrassed) as well!)
