Yes the 'end'-part is done that way: The concave 
shape is a difference between a sphere and a torus.

I have now tried to replace the difference with an 
intersection of a sphere and a torus with the 
'inverse' keyword. (Is this what you meant?)

==> Same result. No change in the reflections. :(

  texture { Soft_Silver }
  pigment { color Red }

No. Just the above two statements.

Extract from the 'texture.inc' file that came 
with POV-Ray:

#declare Silver1_Colour = color  rgb <0.94, 0.93, 0.83>;

#declare Soft_Silver = 
texture {
    pigment { Silver1_Colour }
    finish {
        metallic
        ambient 0.2
        diffuse 0.35
        specular 0.85
        roughness 0.01
        reflection 0.45
        brilliance 1.5
    }
}
