Hand Painted Brass Figurines

Found these brass, hand-painted musician figurines recently at an estate sale and am at a loss to figure out where they're from or anything about them.
Each measures approximately 2 1/2" high and 3 of the 4 appear to have what looks to be bird-like beaks protruding from their headwear. No markings anywhere, including on the bottoms of the bases.
Perhaps some viewers will be able to supply some details.
