Avon Bob is correct about Elmsford. Yonkers used the 300's. But Westchester used to have a larger variety of units designations. Snorkel, Quint, Ladder, Tower Ladder, Rescue, Ambulance, Light Truck, Utility, Air, Tanker, Engine, Mini Attack, Bus, Quick Attack, Jeep, Patrol, Squrt ... I must be forgetting some. Vista is 2561. If you call 60 control they should get you a list.
