As the rather meager evidence is collected with regards to the manufacturing of the 914, it appears that the assignment of VIN, chassis # and paint (code) was done without the usually expected German trait of
exactness From the few color photos that I've seen of the assembly line, coupled with the data available (largely) from this site, it seems to me that the 914 chassis were fabricated and stamped in sequence, selected in general groupings for paint code assignment, then went through final assembly with VIN data applied.
It would be fascinating to see
all the pictures that might exist as prints, negatives or slides of industrial, commercial or personal photographs taken at the Karmann Werks in Osnabruck while the 914 was produced. These pictures probably exist in someones' forgotten photo file, on dusty corporate storage shelves, or in some 35mm slide tray lost in some professional photographers' archival material.
