tokyo2: Dating NR-52F1

Hello,

Here´s the simple clou how to date these japanese world receivers, regardless if branded als Tokyo Skylark, Marc, Shebro or Globephone ICF-2003DX : Just look at the small paper sheet with the "FINAL INSPECT. NO.", in the battery compartment. The first left 2 digits show the year (known values in 2020 are 76-79), followed by the month (known values in 2020 are 01-11). The last 4 right digits give the actual series- No. I´m quite sure they started the series- No. with 0001 at the beginning of every new month.

For this result, I inspected about 15 devices (radiomuseum.org, ebay, further internet pics, own receiver). While maintaining my own "Skylark" I carefully inspected it for for further dating hints, but found no other (except the SN76007 integrated AF Amp datecode)
