This is the NEW IMPROVED Spark-Master.
(as apposed to the old Spark-Master?)
Well I’m guessing this item was meant to fit between your distributor and coil and to add a more powerful spark! Did this gimmick work? I have no idea, I couldn’t find out a much about it, but I do know it would make a cool addition to your collection, sitting next to your diecast cars or on the dashboard of your classic at the next car show. Since it says it works on both 6 and 12 volt systems I’m thinking its from the 50’s – 60’s time period. Condition: Box shows a lot of shelf wear, its missing an end flap but the device itself looks to be in as new condition. Please see photos.
