I like the brass texture too.
In fact I tried to reproduce it - here is my attempt...

Perhaps you want to correct my mistakes?


global_settings {
        irid_wavelength srgb <254,182,89>/255
}

texture {
 pigment {color srgb <254,182,89>/255}
 normal {
         average
         normal_map {
          [1      bumps
                                scale 0.0175
                                bump_size 0.2
                        ]
          [1      bumps
                                scale 0.35
                                bump_size 0.2
                        ]
          [1      function {(f_ridged_mf ((4+x)/0.3, y/0.3, z/0.3, 0.5, 2.7, 4,
1, 1.5, 0)-1.8)*0.5}
                         scale 0.35
                         bump_size 0.3
                         slope_map {
                          [0      <0,1>]
                          [0.25   <1,0>]
                          [1      <1,0>]
                         }
                        ]
         }
                accuracy 0.003
        }
 finish {
         ambient 0
         diffuse 0.16
         specular 0.8
         roughness 0.11
         metallic
         reflection {0.2, 0.4 metallic}
                irid {0.07 thickness 0.5 turbulence 0.2}
        }
}
