What's the oldest tool you have ?

Those are some old tools. I think the oldest I have are a couple of Ford tools that were in the tool box under the hood of my 49 Ford 8N tractor. I also have a 1950s Snap On nut runner. Very similar to an air ratchet, but high speed, low torque for installing tin on an engine on the assembly line. Oil pans, valve covers and such. Only torques to around 8 LB FT, but gets there in a dang hurry. Still works like new.
