Yeah, I took that picture with the tape measure to give some kind of scale as to how big the emblem is. I was originally going to ask if anybody might have any clue what it could have been on originally, but I decided it didn't matter. But since you brought up the tape measure, if I hand him one he'll entertain himself for hours walking around measuring things.
EDIT: My wife just informed me that he's got a little 1 meter tape measure key chain that he wears on a belt loop. He's actually wearing it right now. Wow...
