Here's a listing for an excellent SHEAFFER VALIANT LIFETIME TRIUMPH  TUCKAWAY pen from about 1946.  It is 4-5/8" long.  with excellent trim plating which includes an unusual monogrammed 5/8" wide cap band monogrammed in script and I can't quite make it out... something like Eolinor. The cap imprint is in three lines and remains bold. The plastic,  both cap and barrel are in excellent condition. and the section is grooved for gripping. The metal thread band for securing the cap is loose on this pen and needs to be secured as it requires some manipulation to remove the cap.  The  plunger filler still operates and takes up ink. Nib is SHEAFFER'S, LIFETIME,14K Triumph in two tone color. Looks like a medium width in excellent iridium.
