Re: anyone heard of a Bunn's Warmer?
According to the old ad in the link you posted, the stoves were manufactured by "DeWald Northwest Albany."
A search found this information listed on another website:
DEWALD NORTHWEST CO
33710 Oakville Rd Sw
Albany, OR, USA 97321-9479
One of the current internet links describe the company today as a dumpster manufacturer. And link to the company website I found listed with the above address was broken.
If you zoom into the old ad, you will see that the stove model "IS NOT approved for use in a mobile home!" for whatever that's worth.
Someone said "Making good decisions comes from experience, experience comes from bad decisions." I say there are three kinds of people: those who learn from their mistakes, those who learn from the mistakes of others, and those who never learn.
