As an aside, I have a Bianchi pantographed 3T stem that I had milled out to fit a Cinelli bar back in the 80's which are sitting in a spare parts box in the basement. Who would have known that stem in it's original state is probably a desirable part for a vintage cycling group 30 years later. :-)
the style of "engraving" on Cinelli bars will provide some guidance as to center diameter.
Crest on both sides or one side with different crest for model, most likely if aluminum, 26.4
Winged C Cinelli logo type, and simple model name on the other side, with model name and width noted, like 64-42
most likely 26.4
Cinelli with a pentagram to one side... 26.0 (these were later 80's and 90's)
Model year and Cinelli can be a fraught conjecture. We got orders filled with parts from 2 to 3 decades even. Steel stems with badges, alloy stems with bolts and nuts mixed with allen key styles...
Stampings on top of various styles, some with no stampings.
