This is not intended as a general enquiries thread. It is assumed that you are trying to find a specific mod, that you have made serious efforts to look for it yourself and that you will provide some identifying information so others can help you. Or as Gren put it:
Before You Post Here
Please do your best to find the mod yourself. Most 'missing' mods can be found on http://mw.yacoby.net/ http://www.tessearch.com/ and http://www.fliggerty.com/ http://mw.modhistory.com/. Even the http://wayback.archive.org/web/ can sometimes find lost mods.
Also previous Mod Detectives threads are worth checking as your question may already have been answered.
Psyringe's excellent http://www.yacoby.net/es/forum/12/7235431183639320.html , is a useful read before you ask here.
................................................................
Please repost here any unanswered specific requests from the previous Detectives threads.
I tend to upload mods that have been recovered (currently some four hundred mostly older mods) to http://www.fliggerty.com/ http://mw.modhistory.com/, and encourage others to find permanent download homes for their rediscoveries.

Here are mods that are still missing. If anyone can come up with them it would be appreciated:
.... some mods made by Silver_Falcon:
silver's drowhead or something
... Mage Telvanni Items by sk0rponok?
