Subject: [CR]Geometry of mid 60s Cinellis

I searched the archives for some mention of this, but I only found passing references that used the word geometry in a non-specific way. I didn't find any hard numbers for seat tube angles, head tube angles, fork rake offset, trail, etc.

So I have a couple questions. Does anyone know a source for these numbers for say a mid 60s Cinelli SC? Was there a set of standards that Cinelli built to, or were these things fluid and changing all the time so that no two 57 cm 1965 SC's had the same seat tube angles, or head tube angles?
