There are numerous shows set circa 1950's, but cars, costumes, clothes get confusing anywhere b/w 1940s to 1960s.....most likely
1950-1960s
-- Khun Chai series--- starts in 1957 ..."Mother India" film was showing ... 2nd part starts talking about man on the moon although they are months apart.... clothes and cars are confusing ... some from 1940s, others from 1960s.
-- Neung Nai Suang (2005) --- either 1950s or early 1960s.
-- Mafia Leurd Mongkorn --- could be anywhere b/w 1950s to 1970s (according to cars, clothes and hair styles)... Suer looks circa 1960 ... Krating looked liked 70s (her clothes) ... maybe just bad costumes :P
1970s -1980s
-- Rising Sun Series --- anywhere b/w late 1970s -1980s ... most likely circa 1982 (mainly from Mayumis clothes, but disco scene was 70s) ...
Also ... these ... looked post war to me , so most likely 1950s... NOT before 1945!
