Jim, JT, and Charlie,

Thank you all very much! I'm going to treat the wooden-box-as-rust-
preventer story as hogwash and finish boxes inside and out with
polyurethane. Furthermore, since I live down on the Gulf Coast near
Houston, where humidity sometimes presents a small problem, I'm going
to buy a case of those small cans of reheatable dessicant and clip one
inside every box.

Thanks very much for the help.
Dave
