Weapon & hand textures need restoring

Okay, so when my brother downloaded a weapon pack, it replaced all the weapon textures. Also, when I downloaded a map pack, it made my character’s hands look like Faith (the person for Mirror’s Edge)'s hands. Is there anyway I can fix this without removing all my addons?

Find out where the file is that is overwriting them.
Remove addons one by one to a holding folder to figure out which addon has the replacement, then locate the exact file which replaces the hands.

It’s not an addon problem, it’s just that the packs replace the materials that the weapons and hands were made of. Can you make a zip file that replaces these folders with the original ones (if the folder does not exist, do not include it):

garrysmod/models/weapons/
garrysmod/materials/models/example/
garrysmod/materials/models/v_crowbar/
garrysmod/materials/models/weapons/
garrysmod/materials/models/weapons/v_hand/
garrysmod/sound/weapons/357/
garrysmod/sound/weapons/physcannon/
garrysmod/sound/weapons/pistol/
garrysmod/sound/weapons/shotgun/
garrysmod/sound/weapons/smg1/

Please help!
