Rare Antique Carved Pipe, Civil War Officer, Sterling

An unusual antique carved pipe showing a Civil War officer charging with sword drawn, surrounded by brick walls with trees above; carved decoration underneath.. Top is silver and marked "JPG, 381, Argent" underneath a shield with chevrons inside, and what looks like "56871." My research reveals that the shield with three chevrons and Argent (French for silver) underneath is the hallmark of the principality of Nenchatel in Switzerland from the 1860s. I just found the hallmark "MFB" on the metal (looks to be brass, but I don't know) around the opening to the pipe. You can see it in the photo showing the opening, though it is too small to read in the photo. The stem is missing. I do not know about pipes, so please ask questions. I do not see any cracks. T is a tiny chip in folliage above one of the brick walls and a small chip inside w the stem goes (see photo). Pipe is 3 3/4 inches high to the silver top and 3 1/2 inches wide measured from the side. This was purchased at an estate sale for an antiques dealer.
