Check the listing for details. NOS Horolovar 400-Day Clock Suspension Spring Unit No. 43A. Condition: New. Listed at 17.25 USD. Horolovar suspension units are equipped with a Horolovar temperature compensating suspension spring, and are assembled in single purpose jigs. I did open a couple samples to examine, and even though they are old, they appeared to be in good shape.
