Re: Oldest Varicoupler Photo
I found this group called the "Xtal Set Society" which published a
picture of a 1922-vintage variometer in their May-98 newsletter.
It's round, not square, but otherwise looks a lot like yours.
Perhaps yours is even older.
You might want to contact them and show them your photo. They can
probably pinpoint the era it was made.
