[IRONCLAD]

Morning, Gentlemen.....I have just purchased an older Jacobs Capacitive Discharge ignition box on E-bay. It appears identical to the old ones (maybe a Grant unit?) that Baldwin-Motion had on their Phase III camaros in 1968-72. It is rectangular with raised rows on top in almost a triangle shape; a recessed square in the middle where Motion put "Phase III, Phase III, Phase III" in lieu of the manufacturer's decal. My question is what color was the BALDWIN-MOTION unit? (the Jacob's unit is blue)
Thanks for any help in this matter.
