1920 Advertising: 1st Ad for the "Short Drum" Stoves.
The short drum burners operate on the same principle as a modern Japanese wick heater.
Here is the 1st advertisement I have seen for Perfection's Aladdin Aluminum Cookware.

Note in the Ad copy, a mention of a Gasoline stove?
1930 was the final year for the Superfex burners. Note the advertisement contains ranges with all Superfex "Fast As Gas" burners, only to be gone from the lineup the next year with the introduction of the new "High Power" burners.
The final major stove update for the Cleveland Foundry / Perfection was in 1931 when the "High Power" Burners were introduced. They used the same 331 wick, which is the same size as the older #21, but the burner and chimney were improved again for even better air flow and a hotter burn, with an output of approximately 7500 Btu's per burner.
Here are the burner output calculations.
I can't find a mention of the "Superfex" or "Double Draft Blue Chimney Burner" after 1931.
Here is the single page color advertisement for the new "High Power" stove burners.
Here is the two page color advertisement for the new "High Power" stove burners.
Here is the Dealer Sales Brochure for 1931.
Here is a window poster from 1931.

The 1950 Perfection "Gas" Range Flier
July, 1952 in Bogota, Columbia, South America.
By 1954 Perfection was selling gas heaters.
Perfection was now "Perfection Industries" and a Division of Hupp Industries.
The venerable utilitarian 525 heater was reduced in quality to the 525M to cut costs but it still sold for $139 in 1955. That's $371 today! They were pricing themselves out of the market.
From the May,1955 issue of Practical Builder:
Gas Heater Brochure
In 1981, Perfection-Schwank apparently dumped model 770 Perfection heaters at cost thru "The Energy Warehouse" in Wood-Ridge, NJ.
Note the absence of the Perfection triangle insignia.
Also note the #500 replacement "Long Life" wicks were referred to as "Inner-Flow".
I will continue to add information as I find it.
