I would like to make a key for it as I don't have one.
I have shimmed the lock open and can unscrew the collar that holds the shackle.
I believe that restoring this lock would be similar to the process described elsewhere for the Yale 805F push key padlock.
This model has a warded keyway so does anyone know which key blank I should get.
Thanks, I have added photos.
I have also added a copy of the lock with info from the 1926 Yale Catalogue.
