Something that pulls over 8000 watts of power better be able to do more than just dry laundry! Bet one or two of those dryers going at the same time could brown-out the entire area back in their day. *LOL*
Now how freaking cool is that?! I've never seen such an attachment before. I've lived with both a '59 LK and a '60 Model 80, but neither had a room heater attachment. Thanks for the pic; once again, I learned something new today.
