Whats your oldest personal possession

The oldest thing that I have is a gun cabinet that my great grand father and grand father built.
This would have been prior to WWII.
I also have a 20 ga. that my grandpa (dad's dad) bought when he got off the train after returning home from WWII.
As for me, I have a neat Marx Army Truck. My grandpa (mom's dad) gave it to me when I was little. It was old when he gave it to me, but still new in the box. Mom swore he bought it for one of my uncles, but misplaced it. The only reason I got it was because he found it again. I never took it home and only played with it when I was at his house.
I've been collecting toy army trucks since.
I also have my teddy bear from when I was little.
