Very nice
That must be one of the first Mark 27's made, as I believe '60 was the first year for these ranges, that are based on the 27" built-in wall ovens.
My neighbor up the street has a newer one in Almond, with self contained controls. It replaced the original installed in '72, which was Avocado with hood mounted controls.
My friend Glenna C. got one of these when she remodeled her kitchen in about '63 or '64; it was Shaded Coppertone, with oven window and self contained controls.
Like the separate control panel on yours, and it looks good in Woodtone Brown. I've seen them in just about every GE color except Cadet Blue (too early) or Sand.
