My husband and I actually live where this school once stood. I really enjoy your project to preserve local history, and we were talking about the fact that we have the original blueprints for Koppel and Beaver Falls if you’d like to photograph them and add them to your site. We also have friends with photographs of the old Koppel school; you could probably interview them to get more information. We’d be happy to help you! Feel free to email me.
