Ambassadeur 2500CI (A-A25-0CI-M-002-N-C) One of the first model produced under the distribution of Mamiya. With huge quantities produced, these Ambassadeur 2500CI were also considered easier to find as compared to her cousins. However, not many of these original boxes survived over the years. This is the first CI model (produced by ABU for Independent Dealers) and was not fitted with a Gold ABU Emblem. Gold ABU Emblem was an icon for all CI model produced in 1996 and 1997. A round Counter Balance fitted only on some of the CI models. Share this:FacebookX
