Well I have this very easy 40mm Sterling lock. My god is it easy to pick, I'd really like to get inside it and find out why! It has no observable screws etc to take it apart, does anyone know if its possible without machine tools?
I don't know the brand but when its unlocked can you see if there is a screw in where the shackle goes, if there isn't you probably can't pull it apart without having to drill out the brass plugs on it.
