We need to build a site like that for US telephones, organized by manufacturer and model number, with "quick find" pictures. It could be done as a wiki so it wouldn't be a burden on one person to maintain: any qualified person could be authorized to post articles. It could consolidate all of our practical knowledge about how to service and maintain telephones, into one place. It would encourage people to write articles for the permanent record. And it would be a major resource for people who are new to this and have questions.
