Would the English military have had access to these size

Copper oxide was used for quite a while.

The "whistle" rectifier in Lionel train transformers of the 1950s were
copper oxide.

Hi
Copper Oxide have the advantage for things like meters
and battery charges because they have a low forward
voltage drop. The primary problem is that it has a very low
reverse voltage. Even in charger applications, it took
a stack of many junctions to hold off the reverse voltage
of a 12volt charger.
