Is it possible to find tag-info (tag-wiki and tag-excerpt) for the tag which was deleted?
I ask because sometimes it might be useful to see the information in those tag-wikis. For example, some of the information could be added to another tag.
To mention a specific example, a tag named (double-factorial) was created on math.SE. After some discussion it was generally agreed that it is better to have this question tagged (factorial) and remove (double-factorial) tag.
Let's say that someone wants to mention in the tag-excerpt/tag-wiki that this tag is also for questions about double factorials. It seems reasonable to check the tag-wiki of the removed tag. If it had good description of double factorials, it can be (at least partially) copied to the tag-wiki for factorial.
In this particular case I was lucky enough that there was a suggestion for the tag-wiki by low reputation users. So by going through review history I was able to find a review of this suggested edit here and here. From there I was able to find link to revision history for the tag-wiki and tag-excerpt. (I would probably have found it faster by checking the tag-creator activity tab, since the same user created both the tag and tag-wiki.) EDIT: Actually, after Revetahw's answer with the Wayback Machine snapshot was posted, it revealed that there was one more "reincarnation" of the same tag with this tag-wiki and tag-excerpt.
Is there an easier way to find tag-info for deleted tags? Would it be possible to find those links if I did not know who created the tag-wiki and if it wasn't shown among suggested edits?
