I was looking at the Fallen Flags site, and there are two FP-7s in the Frsico section, 5042 and 5044. Both have single headlights. Just about every other photo I've seen of Frisco FP-7s shows dual headlights, and Mike Condren's roster states that FP-7s had gyralights added. Does anyone know when they were added? I'm stripping and painting an Roco ER FP-7 with a single headlight, no DB for Frisco--can't afford Intermountain.
