I recently acquired a ‘57 Westinghouse black and white table top set on the Bay for $75. Since it resembles its uber-rare color sibling, I’ve decided to undertake a resto-mod project that will replace the guts of the black and white set with a color chassis. Any thoughts on a suitable color chassis that might sub into the Westy cabinet without a ton of modifications? Appreciate all input. Thanks!

What ever color CRT you can mount in that cabinet, I would then go with whatever chassis it uses.
