Where do I find the HUD Grenade Icon?

Im trying to replace a bunch of custom made grenade Hud icons for the Hotline mod but I can't find them anywhere. does anyone know where i can find them? im looking for the frag, dynamite and the molotov.
This is what im talking about.

No bumping please. I believe they are in one of those _atlas files.
