Medieval personal seal matrice with two birds in a bush

This is a nice medieval bronze seal, dating to the 13th - 14th century. The seal is cut with two birds sitting in a bush or tree. It is inscribed around in Lombardic lettering: +S'LORENS'MAHON* reading as the seal of Laurence Mahon, possibly the tree is s play on the name Lorens with a laurel tree? the seal is nice with a good patina.
