Per Know Your Czechoslovakian Pistols (R. J. Berger, 1989) "rid" is the "Military Code of Ceska Zbrojovka Factory".
Cold War Pistols of Czechoslovakia, (James D. Brown, 2009) devotes pages 65-106 to the Vz52 with many pictures.
I highly recommend this book, it has large glossy pages with a lot of good pictures.
The "A" series serial numbers started in 1953. They were considered "alpha" series so the serial number did not contain leading zeroes.
Since the "F" series began in 1952, I do not believe the story of yours being part of a pre-production run of 200. Each letter series was supposed to run to 10,000 units.
The T in a circle is a Czechoslovak Military proof mark and stands for "Tormentacni" (p. 96 Berger Ibid).
The crossed swords are a common Czech military proof mark.
