Mark on bottom looks like a Greek capital S (Σ), or less likely a capitol M.
The statuette is in excellent condition, with deep carving. The lamb and lion represent universal harmony, while the angel can be considered as the angel of peace or a guardian.
In iconography, the baby in this pose symbolizes an older child rather than an infant. He is offering guidance to the observer. If the female figure did not have wings, she would likely depict the Virgin Mary.
Very clean, no damage. Smoke-free, pet-free home.
