Welcome in 504cc.com Practical Section .
This section will never be ended . I hope you will help me develop it quickly ! I am open to every idea and will accept your demands, just do it by mail! As for User Manuals, it's a pretty long work to scan it especially when you do not own it ... So if you own any that is not available on the site, I'm interested in ( originals, scans, photocopies ! ) ... Enjoy !
