I"m not exactly sure what rigs they were running but they were a seperate Engine and Ladder that always responded together as one company with one officer. I believe the manning was four on each, which included the company officer. On the radio they would be referred to as "Combo 151" etc. I believe most were in Staten Island and a few in Queens. As I remember, the helmet fronts were half black and half red with the number in it. I don"t have that chart but I would sure like to know the Combo Companies that were listed, I think there were maybe ten altogether. I do believe they used the standard FDNY Engine and Ladder Appartus at the time.
