In this 703F has somebody put a lot of energy on the nickel plating the heater. Even the burner is nickel plated (but not the nozzle ). Is in a great condition but i believe there is some areas where is gonna be a challenge to make it tight. I think it's gonna be a shelve heater ( at least for now). The burner is the right burner. I'm missing the flame protection inside the burner (that metal ring) and the original heating doom.
