That is so -- for RCA in the fifties. What ticks me off is when, in the next decade, RCA went to letter date codes for their 7- and 9-pin tubes.
As some of you know, I am slowly working on a 1956 Philco model 22D5102 color set with the TV-233 chassis. In the set, a Philco-branded, SYLVANIA-built 6AW8A date code -- for the 30th week of 1958 -- is "58 30", with the 58 stamped above the 30. However, a PHILCO-built 6M3 damper in the same set is stamped "249". I speculate based upon the history of the TV-123 in question that it stands for the 49th week of 1962.
