The majority of A-11 Dials are not Radium, the numerals and tracks are simply printed in White.
As in the White 'NAVY-RAD' (radium) A-11 Dial shown below (#66-40) this one is Black with radium numerals, most likely the Dial designated 'RAD' (#66-2) but missing from the sample card.
The nicety is the Casebacks 'R' appendix to the model # matches the Dial characteristics bolstering the Watches authenticity.
as stated, the first I have seen.
