I think that's what I wrote. That's all I can remember writing anyway.
The difference between the B&W standard and the CBS color standard was mainly this: receivers made for the former were incompatible with the latter due to a difference in scan rates. ISTR a distinction being drawn between *adapters*--which allowed color broadcasts to be received in black & white and *converters*--which provided for connection to a color wheel.
The gadget in the auction is referred to as an adapter-converter. Notice it has a three-position switch--standard, b&w-from-color, and color. From what I understand the image size had to be reduced for use with a wheel on larger screen sets. So the second switch position would allow you to watch a CBS show full screen--in black & white--and the third position would shrink the raster to fit a wheel.
In either case the device only changed scan rates of the receiver, it didn't actually convert CBS to NTSC.
