It's hard to tell about either the ovens or the drop in.
I don't think I have ever seen a Frigidaire drop in with
an oven window , which is not to say that they were never offered. I don't think those chrome frames around any of the oven windows look Frigidaire-ish. I think on the small drop-in
Frgidair Ranges they had "tower clock/timers" . The tile sure is neat. My parents next door neighbor remodeled her kitchen in the late 50's around a 1955 30" Flair that she had, using those stainless tiles for the back splash above her single stainless sink counter top unit. She even had the stainless front panel timer on the bottom Frigidaire spin tube dw.
