A blonde Zenith porthole possibility

[Kamakiri]

I'm going to check this out on Tuesday, here's the story.

This guy's father opened up an appliance business in 1946, shotly after the war. Appliances trickled in slowly, and in fall 1947, his dad got in a Zenith 10" blonde console, and promptly put it in the window of the shop, with an outdoor speaker. It was used for a year or so in this capacity, being the first TV set in the area. It remained in the back room of the shop until around 1960 or so, when they decided to bring it home and use it, where it was in use until around 1968 or so, the last time it was plugged in. According to him, it has all of the original literature and even the price tag. It does not have double doors, and it has two chassis. Supposedly in near mint condition.

What's a good value on this set, assuming it is as I'm told? He wants around $150 or so.
