Dating evidence and reference verification

Sources: In Quiet Detail — Primary photographic and collector reference archive

Supporting comparison: A useful illustrated or photographed comparison. The feature alone does not establish a unique production date.

Reference verification: Historical illustration or documented comparison; not an independently authenticated specimen photograph.

Dating caution. This is a documented period reference, not proof of a precise manufacturing year. Case and insert can have different manufacture dates; inserts may have been replaced. A single feature does not establish authenticity.
