...haven't found any confirmation for my thoughts yet.
1. I haven't found any confirmation from which era these pieces origin exactly.
2. I don't think that Panerai supplied stuff to French Navy ever.
3. We know (from some torchs and watches
) that Panerai bought instruments or semi-finished instruments to improve them by theirs own knowledge, know-how and patents.
These allow many implications...Were these pieces produced by Panerai and did they sell them to others, or were they produced by others and supplied to Panerai semifinished to get a Panerai dial?
Happy thinking...I'm thankful for all input!
