I am a younger guy, I purchased from a fpn user a beautiful pelikan 400NN OBB not sure if the nn is appropriate, it was the classic green striped barrel, the nib was perfect for my hand writing position, I carelessly left it on my car roof while working inside a leather organizer, and it flew off the roof, I looked for hours, payed 300 in 2019, and for 3 years have been seeking a replacement in vain, I have found obb nib for sale, but I don't want one that isn't origional to the barrel of the pen, I've periodically searches for a replacement from ebay to here only to never find one, I'm desperate for the affordable luxury writing of that 60s 400 obb it just hurts my heart to think it was taken, the obb nib likely sold for gold spot price where I live, any help you can provide would be met with the utmost gratitude, I have another 400 f nib, it's just not the same...😔
