But without doublechecking I think there are more CTC2-Bs accounted for than all the remaining CBS-Columbia 15- and 19-inch production models combined.

Then there's models from Westinghouse (rectangular 22"), General Electric etc. that quite literally never show up anywhere...but sure would be rare when and if they do.
