Similar year to our yellow Custom Deluxe? Ours has the same quad burner control arrangement on the right, but full glass panel and rotating digital number timer.
At first, I was wondering if the oven door handle might have been replaced on my range as it doesn't look like those on other similar ranges (including the non Electri-Clean version of my range, the RDG-38S) but I saw in my pictures this "S" series Custom Imperial range which has the same handle design as mine.
Note that even the TOL "S" model from 1971-72 lacked the chrome trim on each side of the oven door that your newer Custom Deluxe and some older models had.
