Since the above post, I remembered I not only had once used a gold nib pen, but owned--and actually still do own--the pen. I'd forgotten about it... (Today's lesson: be very careful about using the words "I never" because it can so often come back to haunt you. 😆) That pen, however, was a used/vintage Sheaffer Snorkel desk pen I got and used (only lightly) over 30 years ago. It was last used in 1992 or earlier. At this point, it would certainly need work. I just looked and it says "14K' on the nib, so I assume gold nib. I also had back then a Parker desk pen, but I don't know what kind of nib it had. It too was last use more than 30 years ago.
I also might admit that my Cross Radiance--in occasional use--has gold plating, but it's only plated.
I have a boring black Cross Radiance, but I found an interesting one pictured on-line. Thankfully sold, so I won't have to worry about caving to temptation...
