Damascus Gear
Corrosion on the gear on the end of the camshaft on a wrecked motor in Datchet Downs Station in outback Queensland.
The pinion gear at the bottom left of frame is on the crankshaft and this gear drove the cam shaft in this old pushrod engine. From the corrosion patterns on this gear resembling Damascus Steel, it is evident it was forged. Couldn't imaging forging that today. I would expect it to be machined from billet.
