Are you sure it was only made in 1949? I have read in a couple of places that the 9-425 was made in 1948 as well as '49.

It does indeed have a 7-inch screen. It is shaped like a suitcase, for portability reasons I imagine. This is a fairly decent image of what it looks like:

The television in the photo has been restored so unfortunately I cannot rely on that image for complete accuracy. Our knobs seem to be different; they are smaller, about an inch in diameter and brown. The channel select knob seems to be a replacement, it is larger, black, and is a slighty different shape than the rest. We have the copper plate behind the knobs and it is in fairly good condition, considering its age. I have not tried to use the set yet so I cannot say whether or not it actually works. Also we did not receive the cover piece for the front.

Edit: I forgot something. Ours has a leather handle on the right side of the case (if looking at it from the front).
