Matin & Dejean (Charles-Denis-NoÃ«l Martin & Joseph-Philippe-Adolphe Dejean), of 24 parvis Notre-Dame, Paris. The mark was registered 23 Nov 1837 and cancelled 2 Sep 1846.
It's a pair of wine & water flagons with a basin. Matin & Dejean specialized in table silver, so it's probably not an ecclesiastical set, but rather for secular use. You don't give the size; some smaller sets were used with rosewater at the dinner table for guests to rinse their fingers between courses. (The sets were replaced by finger bowls around this time.)
Nice set - period Louis-Philippe! A good silversmith could (and should!) copy and repair that missing lid.
