1600 Series cars
Lionel never produced a specific "Flat Car" in the 1600 series of numbers. The frames of the 1600 series were all Black in color, but nothing of that series, (Box Car, Tank Car, Gondola) look like they could be used to create this spotlight car. The only single spotlight cars were the 620 and 2620. The 620 gets eliminated because of the Latch couplers, which would indicate it being the 2620 with the Box Couplers. The biggest issue is the color, that was used by Lionel as being RED on the 2620. Everything that I look at, besides the color issue, indicates that it has to be a 2620 Single spotlight car.
