Sounds like a great idea but what exactly are you looking for. I do extensive patent research on US locks, safes and vaults, matching them to actual known products whenever possible. From experience I have found that more often than not if something was patented, at the very least a prototype was made. In some cases patent dates found on a product only relate to some particular aspect of it, often confusing the actual date of the introduction of said product. Knowing that many collectors are interested in dating their finds, including patents and patent dates will usually help to establish that goal. Let me know how you feel about including patents of locks where there are no known examples, otherwise you may find the wiki filling up with the hundreds of patents that I have not yet matched up. I do feel that dating each entry should have a date (patent or manufacture date) so when you have collected numerous entries on Chubb locks for example, the reader will be able to get some sense of sequential history and development. If the dating is later found to be incorrect it could be amended.
