A Kepi... hmmm. Also, do you have the Navigator's Full name (It makes research easier to have full name rather than last name only xD)? And what other cool stuff did he leave?
I don't have the patch with me. It's in the next province over :P
But I'm going to be going there fairly soon so I'll look.
As for the other stuff, there was a really nice compass, some really old backpacks, knives, gun cleaning sets, a film splicer, a slide show projector, and 8mm film projector, a bunch of slides and some 8mm film reels.
We watched a few of the reels (because the projector still works) and there was some pretty neat stuff. Mostly building houses and what have you from the late 40s.
