The 21-CT-55 was RCA's second production set. It was introduced in November of 1954 and was made for about six months. It uses a chassis that is very similar to the CT-100, and a 21AXP22 metal cone picture tube. The picture tube appears to be original and is good. Based on the serial numbers of surviving 21-CT-55s, it is likely that only about 3000 were made, and, as a result, these sets are more rare than the CT-100. Thanks to John Folsom for locating this set for us. More information on this set can be found on Ed Reitan's site. A list of the serial numbers of surviving sets is at Pete Deksnis's site.
