1850,s Pontiled Blacking bottle with dauber intact

I got this blacking bottle diving the bottom of a river a ways back. It dates back to the 1850’s, with a sharp open pontil. It was full of silty mud, with the cork still jammed in it.  After working out the cork, and draining the silt out, I found that the metal dauber that was used to spread the blacking polish was still in it!
