The link (1st ref.) will open to the appropriate page, then just
scroll down. This a very good site concerning the Germans during WWII.
I believe it was the
last chart at bottom, that shows how ineffective the allies bombing raids were on certain heavy industries including
tanks building facilities. All that armor and no properly trained crews to man them all.

The second also a very good site and is linked to their Forums page which should provide some useful info as well.
