L' Abielle seems to have been a dealer of firearms for special occaisons (fine sporting guns). They were located on Rue Turbigo in Paris. They sold guns under their name rather than make them themselves, but maybe they did manufacture guns at some point. I see them as a smaller version of Gastienne Renette.
As to who made Darne type sliding breech guns....well...Darne made the most...but you can't rule out Charlin, Alexandre Bayle, Meyer, Clair Freres, Soleihac, Verney Carron, Lebel (Chatterault), Chevalier, and quite a few others.
Charlins cost more to produce than Darnes...so my guess is a L' Abielle sliding breech shotgun is probably a Charlin.
