I have copies from a 1970s British magazine which mentions the Ambrosio becomeing TTT. It's pretty evident when you compare "late" Ambrosio stems with "early" TTT stems... they are identical. Also, I have yet to see TTT mentioned in new bike catelogues before the mid 1960s, or Ambrosio stems mentioned in new bike catelogues after the mid 1960s after about 1965.
I have never seen the 1A-copy Ambrosio... could I be wrong about this whole "Ambrosio-becoming-TTT" thing?
