Pretty charming stove! If there were a limited model range (no pun intended) that Poppy is available in it wouldn't surprise me that this might be the only 40" (sans a second oven, even) that it can be colored in (& at least w/ a Speed Heat element)...
This one appears unshaded (at least on this monitor), so likely would be the "Terra Cotta" color. If it's from the 60's, it could be "Matador Red", but I think the clock and control panel was different then.
