Between Stefano's (1 of the authors of the Daytona bible) & Mondani's (Mondani is considered to be 1 of THE Rolex authorities by most of the major auction houses), I think the case of the albino '42 was settled some time ago. What I find interesting is that Stefano's dial is slightly different than Mondani's (which looks similar to mine, which was repainted by KR)
As was mentioned some time ago, I believe these white dials were created either as prototypes or small-run marketing tests & not, as popular Rolex lore suggests, to placate PanAm ground crews.
