The artist’s name was Ellery Knight. Thanks to Dario for sending us the information! You can see the original post at http://www.scrimshaw.com/mystery-artist-16-knight/ and the information Dario has shared.

There are several other mystery artists we haven’t been able to match, and if you have a piece of scrimshaw you’d like us to feature on our site to help you find and possibly connect with the artist, please contact us at “firstname.lastname@example.org” with the subject “mystery artist”. A good picture of the work along with a close-up of any initials or signatures helps. Also let us know where (what city/state) you found the item – scrimshaw artists are all over the states, and all over the world!
