Once more, thanks to S. S. Stewart!
1949, and a last gasp for the Stewart name about which I was not previously aware. (Joel, do you have one of these in your collection?) It has a "pilot light." (No doubt a carryover from the old gas days. Watch your eyebrows!)
This image from a circular currently up for auction on eBay, just in case someone wants to bid on it.
Very best to all,
