Tung Sol (TS) headlights were used at the Metuchen plant. There will be a small mfgr part number on the backside of the bulb, but essentially they are listed as 6-inch low/high beam headlight. The Ford script logo should be etched at the center of the headlight and a TS logo (Ts in a circle) is at the bottom of the headlight.
BTW, I have installed the Wagner Ford scripted reproductions in your light buckets. !00% accepted for MCA judging.
