Line 526:

The [[Reference:16520|Daytona 16520]] and individual manual-wind Daytona pages compare serials with dial and component changes. For long-running references such as the [[Reference:5500|Air-King 5500]], compare examples from the relevant period; one broad serial span cannot describe every configuration.

For ref. [[Reference:3358|3358]], Antiquorum dates case 51,419 to 1942, while the chart transcribed above brackets that number between its 1935 and 1940 entries. Auctionata dates case 299,752 to circa 1940. These are catalogue attributions, not a production range; the serial chart is a reconstruction and its entries are selective. For an imported pre-1948 case, date a Glasgow or Edinburgh assay mark by that office's own sequence where one is present; use the serial chart as a cross-check. The two 3358 catalogues do not report assay marks.

A different reference stamped inside the caseback needs comparison with documented examples of that model. Assess the fit and markings together before accepting the back as original or period-correct.
