Not all of the Facile Princeps actions have the complex ejectors. Many use the Baker ejectors which are housed in the forend and are not particularly complex. The tricky ones are the "self-acting" and "unique" ejectors. Both of these ejectors work off of the mainsprings to effect the ejection. You can identify them by the arrangement of limbs and projections mounted on the front lump of the barrels. I have a G2 from 1899 which has the "self acting" ejectors and thankfully they work just fine. It is an ingenious system by must be tuned like a watch. Very few gunsmiths understand how they work. Did you look at the ejectors?
A picture is worth a thousand words...
