Zenith TV: Color Roundie or B&W?

[sean]

Someone fairly local to me is selling a Zenith TV/Radio/Phono combo. The model is a L2310W (chassis 23LC45Z1). I don't have any service info late enough to see if this set is color or B&W. If Zenith kept the same model number scheme that they used in the '50s it would seem this is a 23-tube set. Seems a little light on tubes to be a color set but I just wanted to check. Does anybody know?
