This is an excellent example of the ever-popular Imperial Fountain Pen made by Sheaffer. It dates from the early 1970's and was made in the USA. It is made from Sterling Silver and finished in a diamond pattern which looks superb.
The pen is fitted with an inlaid 14ct gold Fine side of Medium nib which writes very smoothly.
The pen uses standard sheaffer cartridges or an optional converter can be fitted so that the pen can be filled from a bottle of ink.
