I also have an 820, for my vintage fountain pen restoration business. It needs further restoration, for sure, and will get a lot more attention starting in June, because I'm retiring from my professional work at the end of May. So looking forward to really cleaning it up, checking it out for error, and gettting far more proficient. The day job has been getting in the way for years! I used this thread extensively in learning my way around it, and am still learning from it.
