They do quite a range of sizes of the silver tins as "gift boxes" for the tools. I think I have Micra / Squirt Size, Skeletool and I had a Juice KF4 one too.
I have a silver one with a black lid that the 20th Anniversary Wave came in but I've never seen one like yours GG.
I can't see any tins at all in the 2009 catalog, but I bet eleatherman.com, could find out and maybe even source them for you. I'd quite like one of those myself actually.
