Help with French a/c markings ansd serials

[PMoz99]

Hello all.
I am in the process of collecting an building a/c for French aces (and many others!). I have found what I need for most of them, but markings and serials for 3 a/c still elude me. They are -

Yves Carbon, Bloch 152 flown with GCIII/10 May 1940
Roger Sauvage, Potez 631 flown with ECN I/16 May-June 1940
Pierre Poupart, D.520 flown with GCI/3 Vichy France mid-late 1942.

And maybe just one more - I have some uncorroborated info that Leon Richard flew a D.520 coded white 33 when he shot down a FAA Fulmar on 8/6/41 - if this is so, does anyone have the serial number for this a/c?
Many thanks in advance!
Peter
