I finally had some time to play with the pen yesterday. Yes, it fills right up with no problems what so ever. I just used water, and tried the squirt test, and it passed with flying colors. I did a dip in some ink and it wrote a smooth medium line.
The imprint on the side is this one:
W. A. SHEAFFER PEN CO.
FORT MADISON, IOWA, U.S.A.
MADE IN U.S.A.
There is also an gold imprint of the original owner , "K. Mayeda" on the side. I believe he/she was given the pen and never used it.
T.Mann, I think you are right on it being an Valiant. From Richard's site, that pens description matched it the best. Looks like 1952-1959.
Although it appears to have never been used, I am wondering if I should replace the O-rings and ink sac. Being that they are 50 years old.
Now comes the decision of inking it, or leaving it in the box as it is. I love to use my pens, so I don't think the decision is going to be a hard one
