A couple months ago I finally went down the rabbit hole and started collecting vintage pens after wasting some years "hoarding" unspeakable amounts of colors of the very same Lamy pen! So, now that am on this road, can you please point me to the worthy pens on Sheaffer history? There are many, many pens that show for sale locally, so I would like to spot any gems that may be lying around. As for worthy, I don't necessarily mean expensive, they could be ordinary pens with extraordinary details such as the in-laid nibs, the filler systems, or design features worth collecting. Thank you for your help!
