      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.
