I created this database to help others get missing Waterhouse stops.
You can download them and cut them out of cardboard or I can print them for you.
If you are interested in a 3D printed Waterhouse Stop, please contact me here: https://www.markus-hofstaetter.at/pages/kontakt/
If have Waterhouse stops (one or even more) of a lens that is not listed here, please scan them and provide the measurements as specified in the table with the form at the end of the page.
