Sunday, July 24, 2022 -- Old Town Torrance Antique Faire -- Part 7 -- Judson See/Dee Ignition (Judson Res. & Mfg. Co. Conshohocken PA.)

Best I can tell, this product supplements a coil/points ignition system.

Seems like they were used on 50/60s 4-cyl cars (MG, VW, etc.).

 Found these instructions online...
