It is marked BOR on the feed which the seller took for Broad Oblique Right. However it looks like a left oblique in person and in this peicture.
Curved like a left foot. It is a French nib with the thin feed for the original Parker 75. and is marked 585M. It is gold color but does not say 14k. It has the little pennant stamp on it. All of the 75 nibs I have seen have number codes, not letter codes.
Thanks for any help.
