reanimation, sorry: the numeration of the EMC framework is (contrary to appearances) logical - at the beginning they did not have any serial numbers (several dozens of them were built - only frames "suspected" by Ugo de Rosa), then serial numbers without a letter were introduced (exception: designation V, found on unusual frames, for example for 8-year-old Axel or show-offs). Total "no letter" frames were built ~ 1000. Since 1981, the letter designations of the series have been introduced - the first is E. Your frame is 515 copies built in EMC, probably after TdF 1980. You created a masterpiece, unfortunately the stickers absolutely do not match 1980 :(
