Due to the engraving being cut thru the bluing this leads me to believe that Mr. Kuhl was primarily a jewelry engraver who applied his skills to the Remington shotgun pictured. Some call this "pawn shop engraving" though that is usually much cruder. Have you researched the book Entitled "American Engravers"? You may find some information there, most libraries have a copy or can get one on inter-library loan. It has been a while but the book was useful when I was researching an engraver. Another source may be FEGA, the Firearms Engravers Guild of America.
