I found a good looking, good shape Noblesse 585 (14K EF nib) from a local vendor. As far as I have researched, it's a 2nd generation one: brushed metal, no star in the clip, plastic engraved stars at top and bottom. Nib just have the "585" mark. Doesn't have the box.

Where's any online resource I can read to make a list of checks to ensure it is not a fake one. I never bought from this local vendor yet, and MB is a brand which has been extensively faked.

In addition, is a price around $100 ok for a good shape, little typical marks, or excessive as doesn't have box nor converter?

Just will be my first "good vintage" pen, and the most expensive I'd buy (by now I just stick to Faber-Castell or P45) and I want to feel sure about it being a fair trade.

Thanks in advance!
