I found this in Half-Life Source's sprites folder

I'm not sure if anyone else has found this

also I've converted it to PNG using Paint.net

How can you not be sure when there's so many beta mods 'restoring' the old sprite HUD? You've already seen it if you played Missing Information or Insolence or Leaknet, etc.
It's also in Half-Life 2's sprites folder, has been there since release.

Oh, I didn’t know it was in hl2. Sorry?
