I acquired a gorgeous Lady Patricia pen some time ago and used it up until April or so. Great pen, unfortunately small for my hands which made me give up on it. I recently sold it to a buyer in Hungary and after receiving it, he said it writes for about 2 minutes and then stops. He sent it for repair before to discuss further, I hope they don`t brake it, because of my recent findings which I need validated by someone with more experience with these pens.
The Pen is the one from the 1988-1990 catalogue (I have attached a photo of the one I sold). I was using it with Lamy black ink and filled the original cartridge that came with the pen using a syringe. Worked great for many months. I decided to buy Waterman ink and contacted Waterman directly. They replied this pen takes the Waterman International Mini cartridges. I ordered a pack from the local representative and when they arrived, I stuck one in the pen. It was the darkest blue they had but when I wrote, the pen produced very light lines. I thought it might be due to the flushing I did before to insert the new ink (water + some dishwash liquid) but it kept writting pale. As I am using another pen far more often, I stopped using this one and sold it. Gave the Waterman cartridges to the buyer for free.
He reported it would write for like 2 minutes and stop. He cleaned it even with ultrasonic so it should be clean. He then decided to send it for repair. I did some research and found something that might be the cause, but need someone to step in.
The original Lady Patricias were usually with a smooth same color grip section, so this one is supposed to be burgundy. But it had the fine grip type section, same as on the Waterman Executive. I have seen many others like this one posted by other members both here and for sale so I believe this is the way Waterman built it by some reason. Thing is, if this is the Executive grip, it is likely fitted with the Executive feed and unlike I guess the smooth barrel ones which take International minis, the Executive needs a CF. The buyer reported the cartridge fit was too tight and produced vacuum, when he pulled it for a moment and reinserted it, pen started to write again for 2 minutes or so.
is it possible these Lady Patricias (and the Lady Charlotte which also comes with this configuration) need a CF converter and not the International mini? I suspect waterman gave me wrong advice as they might have believed I had the smooth grip one, it is my mistake as I did not send them a picture of the pen.
