G&A or some other of the gun rags did an article on them quite a few years ago. IIRC, it's available online. I'll post what I remember. Keep in mind, it's all from memory and I may have some details wrong.
During WWI, after things settled down to trench warfare, the French decided the wanted more pistols. A LOT more pistols. They contracted with the gun makers in Spain (Eibar region, IIRC) for simple, Browning-type pistols, mostly in .32. The Spanish gun companies then contracted out manufacture of most of the parts in order to keep up with the French orders. Parts, including slides and frames, were contracted out to LOTS of smaller companies and people, including people filing them by hand out of cheap, soft steel in their living rooms and home workshops. This went on for several years, with millions of pistols being delivered. They were cheap, soft steel and parts interchangeability was non-existent, since a lot of them were made, literally, by hand. But, they helped keep the French a viable force during several years of trench warfare.
After WWI, again IIRC, the French collected the "Ruby"-type pistols (as these guns were collectively known, regardless of the make stamped in the gun) and refurbished those that were worth it. With little or no parts interchangeability (including magazines) between individual pistols, I'd bet it was an unmitigated nightmare. I honestly don't know if they sold the guns off or if they stayed in inventory and were brought out again for WWII, but a lot of them were brought home by US GIs after WWII.
As a whole (based on what I have read), if you get a good one, they should shoot fairly well, although for how long would be anyone's guess, since they were largely made from questionable, soft steel on unknown origin. Their only saving grace was that, to shoot .32, they didn't have to be the strongest gun in the world. Parts, including magazines, are almost impossible to find. If yours is a family heirloom, keep it in good shape, maybe shoot a few times it to make sure it shoots, then put it up. If it breaks, you're SOL for parts.
