Re: 1957 Wiper blades

1957 wiper blades did not have a release tag, rivet on top of receiver or patent numbers, with one exception a few examples of 57 wiper blades with a patent number ending in 905. These patent number was used only a couple of years and dropped in favor of patent number 826 and 626.
What is the patent number shown in the judging manual?

There are two type of 905 patent number wiper blades. The early style would be for the 1957, the arm mount did not have a release tag or rivet on type of the mount. Then later style blade had the 905 patent but it was upgraded with the short release tag and rivet on top of mount.
