For auction is a vintage Sheaffer oversize lever fill balance white dot fountain pen with a lifetime nib. This pen is  black and pearl colored. The clip is a  flat ball humped clip I believe- please look at the photos to verify as I am not a expert. The length posted (closed) is 5 5/8"  150mm. When dipped in ink this pen writes smoothly with what seems to me to be a double or triple extra fine line - see photo #10.   Imprint on the barrel- W.A. SHEAFFER PEN CO. FORT MADISON, IOWA. U.S.A. PAT. D- 78,795 .  On the clip- SHEAFFER'S.  On the nib- SHEAFFER LIFETIME REG. U.S. PAT. OFF. MADE IN U.S.A.  5601546.                               ------I usually sell one vintage pen  or mechanical pencil almost every week in 10 day auctions starting on Thursday's.---------
