I am never sure, just sometimes confident.
You're correct on radio models. The changeover for TVs was not abrupt. There were 1953 TVs with "A" prefix as well as 53-. By 1954, more TVs were transitioned to "B" with the 55 "C" line being completed. The TV number system changed again in the early 70s. There were no more domestic manufactured small radios. Sandusky transitioned to auto electronics.
Air conditioners used a similar system, but not in sync with TVs and radios. I believe "M" was '55 and "R" was '56. Different letters were skipped and/or omitted.
On radios, you are the source. I won't challenge that.
