Early french pilots licence

[DRAGON]

Hello everybody,
Just to try and keep the interest alive I'd like to submit this for your thoughts. I know what it is BUT, you'll notice that it is of excepional quality in comparison with all the examples I've seen on various sites, most of which are the ones with 5 digit numbers indented on the lower reverse. It is without doubt made of silver and gold, the real wow is the number on the reverse "18" which is engraved. Also no makers mark at all. My thoughts are that it is an early piece where no expense seems to have been spared, so I would love to put a name to the number if at all possible.I've asked several people if there's a register of recipients but have so far come up against a brick wall. Any help would really be appreciated.
What a wonderful forum this is!
Best wishes,
Dragon

Hello Dragon,

I would be interested in viewing the obverse side of this badge if possible.

Kind regards, Malcolm.

Hello Malcolm,
I'll try posting the obverse picture now. I'm struggling a bit to get the pictures to below the required maximum kb. Here goes.
Best regards,

Hi Malcolm,
I have no early French references but this item was something I just couldn't refuse when it was offered. The workmanship is just so much in a different class than the ones I have found images of on the web. As I said there are no makers marks, no metal content marks just the engraved 18.
The earliest badge I have see was "Tombac" with gold and silver wash in the appropriate areas. That was maker marked with an italic capital B (Bertrand perhaps?) and stamped 4277. Mine looks like a presentation piece in comparison. Any thoughts would be greatly appreciated.
Best wishes,
Dragon
