I think it is from ww1. Found at ww1 camp. Would appreciate any help identifying this, it appears to be thin cooper on front and back, with material in between. Maybe asbestos?
I finally knew one!!!!! It's what's left of a head gasket to a car, or tractor,etc...Engine of some kind! almost 100% positive! Or gasket of some kind! And yes, I do believe the old ones did have asbestos in between thin layers of metal.
Some examples, could even be from a small engine. But the water ports make me think a water cooled flathead, because of shape. Or maybe even exhaust gasket?
You should have seen me posting!!! I almost fell off the couch with the laptop! I was yelling eww ewww I finally know one!!!!! I had to try to get it posted before anyone beat me! Cuz.... I don't know how long it will be, before I know the next one!!!
I don't even care if I'm wrong now!
