Old "HaDees" Heater These old heaters are cool. Every time I see one I have to snatch it up and sell it here. Some guys use these as speaker cabinets!! Firewall mount. Neat "HADEES" logo. Never had one like this before, and I've had several. Has a door on each side of the heater cabinet to control air flow. Knockouts for defroster tube. Only one was used. The slide handle on the cabinet front controls a curtain vent in the cabinet bottom. Unfortunately, this curtain needs repair. Fan turns, but I haven't hooked it up to juice. $85 + shipping
