Help ID French Pilot of Escadrille Hanriot Dupont 174

[Fokker Ace]

We are trying to find out who the person in the photo below might be. He is standing in front of a Hanriot HD.3 C2 of Escadrille HD 174. A different photo of the same aircraft, aircraft 5, appears in French Aircraft of the First World War.

This escadrille formed in October 1918 as the HD.3 entered service, so perhaps this photo could have been taken around that time.

We are hoping someone may have a pilot roster for this group, or even know who is in the photo.

Bonsoir

As you certainly know, a lot of official archives of french ww1 military aviation had been destroyed in 39-40
Hopefully the roster of the escadrille HD 174 still exists but only for the second
quarter of 1919
Looking at the photo,season were it was taken was certainly spring or summer
(of 1919 or 1920 ??)
The pilot( or observer ?) is sous-lieutenant or adjudant
I dont know him , but look familiar

here is the roster of that escadrille on 2nd quarter of 1919
