The e_texturepack.zip file you have requested: Skins / Weapon Pack / Half-Life 2 Weapon Skin Pack - 5.05mb is not available. Perhaps try browsing all files for the game Half-Life 2 and upload any files you want to share or are missing. This is the only information we could locate:
This is a small texture pack that can be applied to a variety of game modifications for half life 2, the example given in the readme is Garrys mod but it could easily be applied to other modifications. This mod adds some interesting new colours to the pistol, the AR2, the SMG1, and the .357 but does not change their actual models.
