i used your rmf definition then tweaked the normal map for this version ...

normal {
   average
     normal_map {
       [1 bumps scale 0.175 bump_size 0.15]
       [1 bumps scale 0.35 bump_size 0.15]
       [1 function { RMF(x, y, z) } scale 0.1 bump_size 0.125 slope_map 
{ [0 <0,1>] [0.25 <1,0>] [1 <1,0>] }]
       }
   accuracy 1e-3
   scale 0.05
   }

... i think it looks like cast brass that's been worked a bit.
