L. E. Waterman Company of New York City produced a tree trunk patterned fountain pen. Circa 1910 - 1920. A mechanical pencil and Victorian cedar holder pencil were also created. All featured a knobby tree trunk section or body. The tree trunk parts of the pieces were likely made by a silversmith in Germany or New York City. The working end of the mechanical pencil was made by Eversharp. It also features a telescopic section. I'm showing examples of the Victorian pencil and mechanical pencil. The Victorian piece is 3 3/4 inches long closed and 5 1/2 inches long with the shown wooden pencil. The mechanical pencil is 5 1/8 inches closed and 6 3/8 extended. I have more than a few pencils (mostly mechanical), in the stash. The Victorian tree trunk is the favorite. Thank you again, Ellen.
