The owner wrote this note:
The models belonged to the grand-mother of my wife. She got them as a gift for Christmas in the year 1891, when she was a child (the grand-mother, not my wife!). The Leo-family at the time owned a brewery in the village Duerrmenz (near to Muehlacker), that is about 50 kilometers from Stuttgart. The models are used, my wife and I tried to make cookies ("Springerle") with them, but it is very complicated and not useful nowadays.
