I Think....
That's a '59, and it's a model below the Liberators and Stratoliners, a more basic model.   The controls tell me it's a single-oven model; there's only one set of knobs for Oven Set and Oven Temp.  There's also no plug for a griddle, and there's no slider control or sensor for Automatic Calrod.
It's really nice-looking!  I cannot tell what that is over on the left-hand side, on the silver aluminum area on front of the console, under the keyboard buttons.  Is something missing there?  It looks like there should be a substantial emblem or something there, but like something might have been removed from the area.  
Anyone know?
