VOLT-TA-DROP 12V TO 6V COLUMBIA Model 12-6pm, original box, new old stock. I believe these were used to drop voltage from 12 to 6 volts back in the 30s, 40s and 50s when cars were converted to 12 volts but still ran some things at 6 volts.
Item is new never used, still in original box, even has the original mounting screws included.
Shipping to lower 48 only.
