Old castell padlock pat n 430168

Nice Lock. This look like to me almost like all the push key padlock (Yale Model 803, 805 and other padlock). Look like you need to push pressure on the lock as per drawing A & B. Maybe using a rope or something to pull on the lock A & B to impression the key. I remember long time ago a guy came up a tool to pull the shackle while trying to pick the lock or impression the key also using a rope. Keep this in mind only use so much pressure to do this.
