This is not mine, and I do not know the seller. But for you color TV collectors, this is a very early NTSC color bar generator, which is fun to work on and use in its own right. It produces true NTSC standard color bars, with proper luminance and chrominance levels, though the bars are not in the familiar "staircase" luminance order. There were very few NTSC color bar generators mad in the tube era.

John is right. I have one in working order and it is fun to hook it to an old color set. This one looks to have the proper cables also. It puts out RF and pure NTSC video on two different cables.
