Wayne,

They may be usable still as your other posts replied.

If your restoration needs to look exact as original built, you have little choice.
If you just need function, then a modern diode bridge is in order.
Copper oxide was popular between tube diodes and better silicon diodes.
But the magic smoke in copper oxide  diodes is more toxic than the magic smoke in silicon 
or germanium diodes. Thus copper oxide has fallen out of favor with
some people.
