Needing some of your expert help in identifying a 1940s heater core I picked up at an antiques sale. I.tested it and there are no leaks with 8psi and the original 6 volt fan was squealing badly until I oiled it. Planning on mounting it under the dash on my 1942 1.5 ton Chevy flatbed for those cold winter months. My question does anyone know what vehicles used Red Cat heater cores or possibly tractors?
