This is a Le Boeuf ringtop fountain pen in brown and black celluloid from the early 1930s. It’s a 4 1/2 inch long sleeve filler pen. It fills by pulling open the barrel at a split in the middle, or in this case at the section, to reveal a metal sleeve with an oval cutout. There is a press bar in the cutout that directly presses the ink sac, allowing the pen to fill. Essentially, it's like a lever filling pen without the lever, with your thumb doing the work. The LeBoeuf Fountain Pen Company incorporated in 1921 at 49 Arch Street, Springfield, Massachusetts, and by 1922 had 25 employees. The company had a fairly short life, filing for bankruptcy in 1933. The ringtop and cap bands are gold filled. The gold nib is stamped LEBOEUF over 4 over SPRINGFIELD over MASS. The barrel is stamped "LeBoeuf" over "PAT. APPL'D FOR" over "SPRINGFIELD, MASS". Le Boeuf pens are noted and prized for their beautiful celluloids. #pencollecting #fountainpen #leboeuf #lebouefpen #celluloid #penhero https://www.instagram.com/p/CLX4L-sDG2X/?igshid=1gwz4ltdz9y70
