Vintage Serviced Kaweco Sonderklasse 683 fountain pen. A very rare and interesting pen from Kaweco, this is the “Premium line, ” or “Sonderklasse” in Germany. It was also called “Meisterklasse” by Kaweco, similar how Montblanc marked their Meisterstück pens. The pen does have some features that weren’t available on regular Kaweco pens from the time, such as a 2- tone gold nib and more gold plated parts and also more components than a regular Kaweco. 14k BB- Double Broad point nib. A very flexible and smooth nib to write with a great line variation. The pen is in mint condition, as you can see on the pictures. There are no visible cracks. The nib writes well and the fountain pen has received a full service, which included full disassembly, thorough cleaning and lubrication of moving parts with silicone. The pens are guaranteed authentic.
