Mint cosmetic condition. This is a Flat top model (introduced in 1975). Rarer Green trim body with steel clip and trim. Green logo and green section.  Cap is stamped "Parker Made in England". No date code so pre 1980.   All steel trim is in perfect condition. Clip is properly aligned and a firm fit. It has a perfect green tab (rare to find in perfect condition as they wear easily over time). Nib is a stainless steel and is in perfect condition. No size marked but it looks more like a medium to me. Dip tested and writes nicely (see photo of writing sample). The pen can use either cartridges or the ink converter filler which is fitted and working when water tested. Parker  box in perfect condition.
