This eBay listing is for a vintage UNTESTED Parker Fountain Pen that comes as you see pictured in the listing and noted above. Based on a Google AI search, this is a Parkette Duo or just Parkette model but the side of the pen is marked Parker Challenger. The NIB is marked Parker Pen, Made in USA, 1. I didn’t see any gold markings on the NIB but it is gold toned. I don’t know much about fountain pens so please ask questions if you have any. Because of this, I have no experience in testing old fountain pens – sorry!! In my option, it’s in nice overall condition.
