A superb example of a Parker 51 Aerometric fountain pen in the very sought after Forest Green with a lustraloy cap and G/F clip with a clear grey jewel. It is fitted with the original Parker Made In USA RU 1948 . gold nib. The pen has the rare screw on sac protector with the Press 6 Times filling instruction. It has been fully cleaned internally and restored and is in excellent condition and writes with a fine line. Will NOT disappoint.
