The Rolleiflex MX or 3.5A in Europe was made from June 1951 to March 1954, this camera production was included in two serial numbers blocks: 1200000 to 1298999 and 1401000 to 1427999, I say "included" because this camera model shares the same serial numbers blocks with other Rollei TLR models, in fact with the 2,8B and 2,8C, there are no repeated numbers for each unit but you find these three models sharing the serial numbers blocks mentioned above. This camera received some changes along the production. There is no a preferred film for these cameras, the choice is for the photographer according his preferences and necessities within the different avilable films for the format.
