Colby emailed me photos of his stove and asked if I was able to tell him how old his Tappan stove is. The stove was purchased with his 1930's bungalow and has the model # W-55.
The stove is obviously pre-Tappan Deluxe...but has essentially the same body as the Deluxe (it's 38" wide). Whenever I see pictures of these earlier stoves, I pull out the Sales Manuals I have for 1940 and 1941 Tappan Philgas stoves. Sure enough, I was able to find an almost identical stove in the 1941 Ads. Colby's stove is not a Philgas, but it narrows down the year of his stove to the early 1940's.
One item, Colby's stove has that the Philgas (model # 541) stove does not have is a timer on the back splash. Tappan also made a Philgas model #741 that included a back splash timer, but had a window in the oven door that Colby's does not.
The Philgas Tappan model 541 sold for $118.50 in 1941.
Colby, what do you think? Make sense? Also, I'm curious...what does that patch on the oven door say?
