Wooden hulled PT boats had 6.6 tons of Cu, Zn, Pb? Hard to believe. That's a significant fraction of PT-20's 40 gross register tons.

Wooden hulls were often clad in copper sheet to prevent worms eating them. Wiring, also. Lead for ballast, etc. Zinc for pot metal carburetors, as well. Didn't mention aluminum, so maybe bronze instead of pot metal. I can believe it.
