I was wanting to know exactly when Cinelli stopped using the Swiss casting foundry George Fisher, to produce their cast lugs for the Supercorsa model?

I believe they went to Taiwan after that, but I'm not certain if that's indeed true, and when.

I would imagine if they did, it would be at the same time (say 1983 or so) when they went from the sleeved seat tube lug (accommodating the 26.2 seat post) to its removal, which allowed the more 'standardized 27.2 dimension.

Does anyone have any insight on this matter?
