The gray clock means ’53.  I have the ’54 with the brick-red clock; the unit itself is Sherwood Green.  I absolutely adore it.  It’s an amazing piece of kitchen equipment.

The burners are the same style as the Flair, but someone else will have to confirm if they are truly identical. They are wired in, not plugged in.  Also, the oven has nichrome coils top and bottom, which might be unfamiliar to you.  I love them, but they are different from the solid coils used today.

For the price, I’m tempted to get this one myself.  I paid a lot more for mine, but the color was rare enough to make it worth it to me.

This is a 30″—a Thrify 30, as Frigidaire called it!  Robert has the Owner’s Manual for the ’54 in his Automatice.

If there’s any bad news lurking around in that unit, it is almost guaranteed to be with the clock and timer apparatus.  Since you mentioned that is an important feature for you, I must unfortunately rain on your parade, at least a little bit.  You definitely want to ask about that.  Also, on my unit, the oven won’t turn on every once in a while, because the timer has slipped into ‘off’ position.  I just give it a twist till it dings the bell, and then everything is fine.  This is something I have been planning to fix since I got the unit, but it’s so insignificant, I don’t bother.  For you, it might be more of a concern.
