They didn't- before the CT-100 there was only prototypes called 'model x', where x was a number. The model 5 is a well known example, and the precursor to the production model CT-100. I have a prototype chassis from earlier on, but no one has yet nailed down exactly what it is. Near as anyone can tell, it was a lab only experimental chassis used to explore the possibility of CPA for color transmissions.

Tidbit: CTC-x only refers to the chassis, sets normally had actual names. See the picture in my signature- Director 21 using CTC-4 chassis, Wingate using CTC-5 chassis, Anderson using the CTC-7 chassis... Ed Reitan has a good site that explains all of this with pictures, he has most of the early RCA stuff up to CTC-10. Check it out:

I was always under the impression that their chassis numbering system started with CTC2, then CTC2a, CTC2b and so forth. I don't remember ever seeing or hearing of an RCA CTC-3 chassis, either.

I'm not aware of a 2A, but the 2B is the chassis belonging to the model 21-CT-55 receiver that replaced the CT-100 and actually uses a modified CT-100 chassis. The changes include a different high voltage and scanning section to drive the larger 21" round picture tube.

Is there a CTC-3? Now there's a trick question you can pull on your friends!

Early color trivia time: In the 21-CT-55 receiver, the main chassis was the CTC-2B, and the convergence panel was called CTC-3 since it was a seperate chassis connected to the main one with a harness. Technically, there is no such thing as a receiver chassis with the designation CTC-3. So it exists, just not as a set by itself.
