Doom status bar texture

[Jarewill]

So, I don't know where to ask about it, but I was looking around for quite a bit now, but I have troubles finding an answer.
Basically, the doom status bar is made out of this nice looking gray texture.

In my search through the game files in SLADE I found two textures that looked similar, but still a bit off.
The "FLAT5_4" lump:

And the "WALL01" lumps: (the texture is split into a few parts)

---

Now, while the second one looks really similar, it still feels off to me, so I'd like to ask here on the forums if there is a known texture to use.
Thanks in advance.

And apologies for my blindness.
