Hi everyone! I'm very new to this forum and just started getting into the lockpicking hobby.

I purchased a Master Lock number 3 recently and have had not trouble at all single pin picking it. I also have a Master Lock 140D to begin my practice with security pins. I found an all brass EM-D-KAY Brand padlock in my garage and have taken an interest in it. I have spent a couple of hours going at it and have not yet been successful. Does anybody know this particular type of lock? Thanks
