I posted on an earlier thread a couple days ago and appreciated the response from tim and jimmi.
After looking at the heater and removing it. It does not appear to be a recirculating heater. No water control valve. No hand lever to switch to defroster. There is a cable attachment to a lever to open and close a flap on the door.
There is an old round Chevrolet label in the front and a manufacturer's label with: Harrison H-02-47.
The unit is in bad shape. rusted though parts of the cabinet. I have not been able to locate cabinet parts. Heck, I'd be interested in a complete re-built one, but have not see one.
any help appreciated.
