This is the Admiral, another of the snorkel filling fountain pens from Sheaffer. It was made in the USA around 1952 and is finished in Pastel Green with a gold filled cap band and clip.
The pen is fitted with an open nib which writes with a smooth Medium line.
The snorkel filling system was unique to Sheaffer and consisted of a narrow tube that extended out from under the nib. This tube is dipped in the ink bottle and used to draw up the ink into the reservoir. This keeps the nib clean and it was an efficient system that worked very well.
The mechanism on this pen has been fully serviced. The pen is in good condition with very minor scratches and wear marks.
