Three cars (#1-#3) built at the Jackson & Sharp Plant of American Car & Foundry, Lot #7530, 1/9/1915, 8 Bench, Single Truck, Gould Storage Battery for power. There was a car #4, but no records show who made it and it varies in design from these three cars. Most likely either purchased second hand from some other railroad, or even possibly home built in Mayaguez (I think it was second hand myself). Dave Deyo.
