Some thoughts about different settings.

ini file: Display_Gamma=1
Using version 3.7, you may want to take advantage of the sRGB colour 
space. Personally, I have my Display_Gamma set permanently to: sRGB.

Pigments:
You may want to play with srgb too inside the pigments. Change all 'rgb' 
to 'srgb' and see the difference. If you want exactly the same output 
you may need to tweak the rgb values, making them lighter.

Textures:
After some more testing and for a better result, I advice to change the 
XE_rusty_steel texture to:

#declare XE_rusty_steel =
texture {
	bozo
	texture_map
		{
		[ 0.0 XE_rust ]
		[ 0.2 XE_rust ]
		[ 0.5 XE_steel ]
		[ 1.0 XE_steel ]
		}
	turbulence 1
	omega .6
	lambda 4
	warp { turbulence 1 }
}

Using sRGB colours without changing their values, you get the following 
image. Left = XE_rusty_iron; Right = XE_rusty_steel.

XE_iron_2 declare, but not used.

Yes, you can choose your own combinations ;-)

I already understood it.
But, it would be desirable to see still options of other users.
Me completely rusty surface interests also.
And, for some reason it seems to me that normal works at the bearing badly.

In p.b.scene-files I have given a collection of rusty metals by several 
authors.

In the image: left = Ke_old_pitted_iron from the collection. normals are 
looking 'normal' to my eyes ;-)

And as I am never entirely satisfied, here is a version with a HDRI 
environment.

Left = XE_rusty_steel; Right = Ke_old_pitted_iron

That was in a thread also started by LanuHum, titled "Rusty bearing".

Well, thanks indeed; I did not remember where I had put it. :-)
