I have owned a Delta Dolce Vita for several years, orange, not exactly sure if there's a model, but it is piston/bottle fill only, i.e., no cartridge or converter. Ever since I purchased it, the threads on the cap have stuck. Sadly, I recently was trying to open the stuck pen, and it broke in half below the threads at the natural juncture - the "break" is actually inside, per the attached picture. It was actually a fairly clean break and the pieces go back together fairly well - see second pic. Questions: 1. Has anyone ever tried to super-glue this type of break? Seems unlikely it would hold ink, but perhaps worth a try. 2. If not repairable, anyone have any idea if it's possible to get a replacement body, or a body from some other pen, that would accept the nib and filler mechanism? I hate to give up on a $500 pen, but perhaps all is lost. I'd welcome any suggestions.
