The tube 1AJ5: 16.Aug.1954 : Electron Tube Registration List. But the Beitman Manual of 1953 brings a Motorola-chassis HS-347 with models 53LC (1, 2, 3) and therefore 1953 seems to be correct.

The series consists of:
- 1AG4 Output Pentode
- 1AH4 RF Pentode (April 1951)
- 1AJ5 Diode-Pentode (August 1954)
- 1V6 Mixer Pentode / Oscillator Triode (April 1951)
- 1AK4 RF Pentode
- 1AK5 Diode-Pentode
Namely the 1AJ5, registered in August 1954, was on the market a year earlier already. Raytheon has advertised this series in the January / February 1953 issue of Communication Engineering and in the March 1953 issue of Tele-Tech & Electronic Industries (see attachment, same ad for both publications).
The Tung-Sol Elekctric Inc data sheet for the tube is dated September 1, 1953. First sets appear end of 1953 e.g. with the Motorola HS-347 chassis.
Obviously, the registration for 1AJ5 was late and has to be marked as erroneuos. In my opinion, it cannot be reliably used to determine the year of a model release.
Kind regards,
