Kommisar - Right now Velobase.com mostly covers information on bicycle components, however I am starting to expand into frames and thus bicycle builders, which a lot of your information that you have gathered will be of great help. I already have a growing collection of bicycle head badges and list of brands that can be added to at any time.
I am looking for people to write some articles on different brands, as well as other topics on vintage bicycles. The range of topics is pretty wide. Feel free to send me a PM (or discuss in thread) what you might wish to contribute.
As far as photos go, I've borrowed a fair few from ebay auctions since that is the only place that many vintage components show up. I do always wait for the auction to come to an end before utilizing the photo(s) in a listing on the website.
