|3" Antique Ritchie Compass CardThis 2 degree card measures 3-1/8" outside diameter with a 1-3/4" white center. The white center would have been cut out to accomodate the float and directional magnets. This card is an authentic early 20th century linen on mica compass card for use in a float-type alcohol-filled compass. These compass cards were recently found in the archives of E.S. Ritchie and Sons. We have only a limited quantity of these, they are excellent for framing or use them to restore an old compass.
