Set of Porcelain Cherubs from Germany

My grandmother acquired this set of porcelain cherubs from Germany in the 1960s. There are four total, each with identifying numbers, seen in the pictures below. The first has a mark of "Schau Bach Kunst, Germany." The rest have a "W" mark with the number 1763. The second figurine has an additional number, 1389, the third, 1354, and the fourth, 1356 (not pictured).
