My initial thought was to buy the 743 or the 823 with the fa nib from Japan, but due to the pandemic, the shipping costs skyrocketed and I was forced to cancel my order. I found a seller on Amazon and wanted to get the forum's thoughts on whether the pen looks valid or not.
The box arrived a little banged up, though the contents are intact. I have a cartridge, user guide, and warranty cards. However, in looking over the pen, I noticed that the feed is grey in color. Is this particular to the FA nib? I've looked online and feeds in the 743 appear to be black in color but I can't tell if the feed is different by nib (WA, PO, F, M, etc.).
I can't tell if this nib is discolored (indicating prior use), fake, or true to form. Any help on establishing the validity (I've enclosed pics of the nib, pen, and accessories) of the purchase would be much appreciated.
