Vacuum tube collection

This is a part of my collection of old vacuum tubes (electron valves).

I have found this stack in my grandparent's cellar and I have not yet managed to identify all of them. I can also only guess at their age and state. Some look like they haven't been unused yet and at least one (RV2 P800) appears to be from the second world war.

If you can provide any information that is missing below please drop me a mail. Thanks.
