Vienna Miniature Bronze Pig

This is a superb miniature bronze female pig / sow figurine I believe was made in the Vienna area in the 19th century. It came with a bunch of much nicer antique Vienna cold painted Bronze animals including some signed Fritz Bergmann but the pig is by far the nicest of the bunch and was not painted so not totally sure where it was made. The figure is much nicer than anything else I could find in terms of modeling and detail. Someone really did an amazing job with this piece even the hoofs are done on the underside. Heavy piece for the size. The figure looks to be in perfect condition. It is marked on the one butt cheek with an impressed F which does not tell me anything but someone out there might know. A little help would be appreciated. The piece is 1 inch tall, 0.75 inches wide and 2.125 inches long. Please email me for more information or other pictures.
