[Valuable] rOtring Rotring *600G Fountain Pen* Silver M-nib

This is a Rotring 600G fountain pen with a 14K gold M nib.
It is a discontinued and no longer produced item, so I believe it is quite rare. There is also a less expensive steel nib version, but the 14K version is more valuable and precious.

I purchased this pen as one with little signs of use, and I have only tested it. It has a very smooth writing feel.
I'm hesitant, but I am organizing my fountain pens, so I will offer this to someone who is looking for it.

There are a few places on the metal part of the barrel with thin lines (I couldn't capture them well in the photos). If you are concerned, please refrain from purchasing.
