I believe this was the Berthier fusil mitrailleur n° 12 - effectively Berthier’s modèle 1916 rechambered for rimless US 30-06 rounds and changes to furniture (while dispensing with the mle 1916’s optional barrel sleeve for air-cooling). Berthier’s earlier fusil mitrailleur n° 3 was also chambered for 30-06.
US Army testers objected to the upwards-pointing box magazine, complaining that the resulting offset sights made aiming non-intuiative (although that was also true for the favoured Madsen LMG). There were other complaints (mainly low rof) but, perhaps, the magazine objection explains image 02.jpg with its underslung box?
The follow-on to this design was Berthier’s modèle 1922 which lost its French competition to the Hotchkiss Mle 1922. Vickers bought the rights to the Berthier Mle 1922 in 1925 and developed it into the Vickers-Berthier series of LMGs. (Berthier had previously developed his fusil mitrailleur n° 12 to fire British .303-inch rounds.) 
This would be a great alternative to the BAR at BR3 an lmg that follows the br3 4 motif of the western allies of highly accurate low capacity mgs. as opposed to the Axis Western allies which rely on less accurate higher capacity mgs. This would make a great bp weapon giving you enough mgs for a full squad with a bonus gun. Following the lewis automatic rifle i would not expect to see this soon, which was nice giving us something bar like at br2.
