I'm new to the community; so a quick introduction seems appropriate - I'm a 'white hat' cyber security expert, which involves digital lock-picking

I'll get to it, I've got an old blue metal box which I have been storing my medicine in - however I've left the key at my folks like a muppet and the backups that I keep on me are - yep you guessed it - in the box.
I've looked around at guides, read this forums rules, but I have no idea what type of lock it is or where to begin. Please can someone assist? I could just bust the box open but that's not a challenge, and I'm not sure how old it is either!


Here are some pictures that I have just taken, if you need some more (Like you want me to take a precise photo inside the lock) then that's no problem.
Thanks All.
