Porcelain Hawks from Tilso

My father has two porcelain hawks sitting on rocks from Tilso. I have searched and searched the web and have not been able to find anything close to them. He is curious about what the value may be even if its $2.00 just because they were his grandmothers. They have no markings on them other then the company and says hand-painted. They are gold and silver looking and the color kinda fades between the two as you turn them around as well as a black tone around the rocks and the bottom of the birds. The figures stand around 7-10 inches tall. I have looked and looked and had other people to look for these figurines and have come up emptied handed. Any possible information on them would be greatly appreciated.

Good
