First, what you have written here, Stuff only equals the first mesh, So 
when you use 'object' the second mesh is not textured.
Your use of 'material { Red }' and the  '#end' suggests that 'Red' is 
defined as a texture and interior somewhere and that the whole code is 
inside an '#if' or a '#macro' statement.
  If what you want is both meshes to be the same color but the first to
have no normal and the second to have a normal. You can use something 
like this:
  #declare Stuff1=mesh{mesh1...}
  #declare Stuff2=mesh{mesh2...}
  #declare Color=rgb<1,0,0>;
  object{Stuff1 pigment{Color}}
  object{Stuff2 pigment{Color} normal { bumps 1 scale 25*0.02 }}

Have fun!
