I was at my local locksmiths yesterday and he gave me this to play with. It is, without a doubt, the easiest lock I've ever picked (yes, even easier than a Master padlock) and I'm shocked that someone actually had this installed on a door at some point. The brand reads "UAP", anyone ever seen these before? It's very heavy and seems well constructed, so I figured it might just have pins removed for some reason... until I picked the other side just as easily.

Here are a couple of pics:
SideFrontAny information on what these are or where they come from would be cool. I've never seen the brand before, and it's probably a good thing if they're all as easy to open as this one was.
