I just got a Yale B50 badlock from ebay, and having alot of trouble opening it. Im pretty sure it has a spool pin, but i cant tell much more. I notced the bottom has a small hole diretly under the shackel, and am wondering if it is made to remove the core. Is there a non-destructive of opening this lock?
here is a photo of the lock for reference:
