Glad to meet another Century enthusiast. The Fultz article is the best single source on the company. I believe, however, that Fultz was very wrong about the early years of the company (and have evidence to support my assertions). Also, Fultz missed that the thumb fillers are imprinted with a die maker's error, and the correct patent date is for Mooney's thumb filler. The library at UM-Whitewater has the papers of Nels Humphrey and minutes from the annual Board meeting for Century, so these are a great place to start if you want to learn about the company. I would also be happy to answer anyquestions that I can.
Thanks for the welcome! I should clarify a bit of my statement about the Fultz article being everything. What I meant to say was the librarians I've chatted with at the library have told me the Fultz article has covered pretty much everything they have in the library so it would just be easier to read that, instead of digging through other stuff.
I have this weird dream that one of these days I'm just going to stumble on a box of Century stuff in some dusty corner of one of the buildings here. Hasn't happened yet! I suppose it would help if I put a WTB out to Whitewater and see if anyone bites out there! Who knows what's floating around in the houses!
