These pictures were taken out of the 1940's Sales Manual for Tappan Philco stoves. The manual also includes a number of non-Tappan Philco stoves (the mentioned Model 440 isn't a Tappan).
I thought it was fun because it shows the Tappan Chromelite cast iron griddle sold as an extra for the early Tappan stoves. It also shows a similar non-Tappan cast aluminum griddle. In 1940, the list price for both of these griddles was $4.50.
The "Thrifty-Maid" Economy Cooker was sold as an accessory to all of the Philco stoves (Tappan or not). List price for the Thrifty-Maid was $8.50.
