Hi, found this at a site that is quite old (1790's) it was found at 8 inches. I got home and was about to throw it out but I started scrubbing it with a brush for the heck of it and seen that there was some markings. As for knowing what it is I have no idea where to start
There are some rather large desk ink well sets as in this photo. This was just MY guess. I'm certainly no expert but if I were and one made a ridiculous guess I certainly hope I wouldn't throw sarcasm and post a cartoon character just to further make a point. Maybe that's just coming from a lady's prospective...
