[Vespers War]

I hadn't seen the Faucon before, so thanks for posting it. Assuming it is using a 6.5mm round, then the statistics are:

Wt 5.5 kg, SA, Dam 3, Pen 2-Nil, Blk 7, Mag 6(c)6, SS 4, Rng 93.

According to the 1910/11 patent (filed 1910, issued 1911), the barrel was 120 calibers in length (my French is just good enough to glean that), so the bullet diameter matters for calculating the barrel length.

Unsurprisingly for an early bullpup, it had issues with the trigger system when tested after the war.

For logistical reasons, this was never going to win out over an RSC using 8mm Lebel. An RSC 1918 was .7 kilos lighter and had the same range, bulk, and recoil, with a more powerful cartridge out of a shorter barrel and similar overall length, and only 1 less round per clip. If the Faucon could get at least two out of the three of lighter weight, a 10-round capacity, and using 8mm Lebel, it might have had some chance of adoption if it was also made mechanically reliable.
