I'll stick my neck out :^) "Westchester" was the parts supplier for Maxwell (United Motors). They supplied lamps, windshields, and accessories. As to which NUMBER (on the top) Westchester you have and its correctness I will pass. There are more knowledgable folks here than I. Westchester made carbide generators, I have also seen a very original car with "Nickerbocker Brass Works" generator that looks just like a Westchester. I don't know the connection with Nickerbocker. There were a couple sizes of Westchesters, I believe. It should mount on the right running board, near the driver. It WAS an accessory, so the buyer may have opted for a Prestolite tank mounted some where else. Magnetos came along in 1910, if yours is a 1909 it should not have one. Jim Dix
