Would you consider an ammo box? They're readily available at surplus stores.

I'm looking for a NEMA type 4 box or equivalent. New one are a bit
pricey. It must be weather proof. Small holes OK, since I could weld
pathes on to keep it watertight. It will be for my 432 beacon and will
be mounted up on a tower (up to 200 feet above ground). Prefer metal.
Size needed would be about 12" X 12" X 6" or so...

Thanks,
