Wild Card made the key point. I have seen those single sided pieces and can only say that they were always gifts, special order items for certain occasions. The Krause PlM from Weitze.net came from a rather small auction house that handled all orders from Oberst Krause. This piece was made by Godet and given by his staff as a gift to him. Just like today those gifts were made by the usuals (the Wagner's, Friedlaender's, Godet's and Rothe's). The feature piece has an inscription on the reverse. von Hauff 1915? Could you confirm this? I do not see anybody with that name or similar name in my lists of PlM recipients. The markmanship may be good enough for a funeral piece, but I am afraid that it is not.
