I keep getting share request from Google drive from users scanning this site and looking for information on these shutters.
I cannot edit old posts therefore I cannot replace the old links.
Thank you for posting updated information. I've worked on so many of the Prontor shutters (and other similar Gauthier models) I don't find I refer to the documentation as much as I used to, but it's nice to have access to it for sure, and there is a least one of them in your folder that I didn't have, which is always useful!
