This is a Sheaffer Valiant II Vacuum-Fil fountain pen in Brown striped celluloid c. 1946. The pen fills by unscrewing the barrel end cap, pulling out the plunger, inserting the nib into ink and pushing in the plunger with one stroke. This creates a vacuum that sucks ink into the barrel ink chamber. Sheaffer transitioned from the rather pointy ended Triumph pens made from 1942 to early 1945 to the more rounded post war pens in 1945 which started appearing in Sheaffer ads by August 1945. The pen is about 5 1/8 inches long capped and sold for $12.50. A matching pencil sold for $5.00. The 9/16 inch wide cap band and spring loaded clip, a new feature with these more rounded pens, are gold filled. The barrel is stamped W. A. SHEAFFER PEN CO. over FORT MADISON, IOWA, U.S.A over MADE IN U.S.A over 1250, which indicated the $12.50 price. The nib is stamped SHEAFFER’S over LIFETIME over REG. U.S. PAT. OFF. over MADE IN U.S.A. over 14K. The Sheaffer White Dot is just above the top of the clip. #pencollecting #fountainpen #sheaffer #sheafferpen #lifetime #sheafferlifetime #triumph #sheaffertriumph #valiant #sheaffervaliant #celluloid #penhero https://www.instagram.com/p/CAJGvAsjB43/?igshid=1ujvfhi7scwai
