This sale is for a new old stock Kenworth truck heater assembly.       I don't know the application, so the pictures and numbers might help a person ID this heater.       The heater housing has the Kenworth logo and the number K142-280 on it.    The heater is a Red Dot brand with their # R-7211-KC on the tag along with a 2/17/82 date.     The Red Dot heater motor has C 3400 G 242 88A P  12V on it.        This is a nice compact heater that could be used in other applications.     The approximate measurements are 12" X 10" X 9 1/2" not counting the copper tubing and mounting bolts sticking out.      As said before this is a new old stock item,  it is in excellent condition.
