C. Hennecke Plaster Sculpture? Plaque?

I have owned this for 10 years.  I purchased it at a farm sale for around $10.  I was told it was very old.  It has a tiny brass plaque on the back near the bottom that states C. Hennecke Co. Milwaukee.  I am assuming this is from the Caspar Hennecke's company that operated in the 1800's through the mid 1900's.  I do not know what it is and what it is used for.  It has a hole near the bottom of the piece under the pot she is cooking as if a light was there, maybe a gaslight, perhaps?  It is in fair shape, not great.  I would enjoy knowing it's use and if I should worry about it's condition.  If it has any significant worth, I should find a better place for it I suppose.  Any help would be greatly appreciated!
