I was wondering if anyone who is knowledgeable about rare Parker 75s could tell me anything about this pen. I got it some years ago from my grandfather when he was alive and it had been tucked away safely in a box for years. Recently I got it out and decided to do some research on it but I couldn't find anything specific about this finish and who might have made it. It has the 750 hallmark on it and hallmarks on the jewels, clip, nib and body.
I would be grateful for any info anyone might have on it!
