Or possibly 1956?

All together now in your best Captain Video announcers voice.

It's Zenith's SPACE COMMAND!!!

Wow, that is cool. I can just imagine watching The Twilight Zone on that.

That's a pretty lookin' Zenith.

I think its a 56. I have the same set in a blonde cabinet without doors. Should be a SC 400.

The nice thing is they're easy to work on (once you heft the chassis/CRT combo out of the cabinet) and they don't have the hard to find 21ep4/21fp4 CRTs.
