There was some discussion of which 1275 cranks are good and bad in the archives, but I can't find this answer. Vizard says early EN16T cranks were Tuftrided, and later ones (1974?) were not. How can I tell which version of EN16T I got with my 1275 bits and pieces? Michael Rowe '74 Midget '60 Bugeye kit Long Island, NY
