last weekend at the Solihull Stamp Society show i saw a Felixtowe 6 registration label on a 1951 Philatelic Congress envelope - i have to say that the fonts and number 6 were different to the ones i have so i still believe that these i have are raf but earlier - can anyone else add to the debate - also if anyone has any raf station registration labels on cover that they would like to sell, please email me -
