Tried in ver 4, but loading obscures the shell. Hope you improve on it. Cheers.

r = 1;  q = 2; L = 4; x = r  Cos[th] ; ; y = L v ; z1 = r  Sin[th] ; z2 = 
  z1 + q*v*(1 - v);
 shell1 = 
    ParametricPlot3D[ {x, y, z1}, {th, 0, Pi}, {v, 0, 1}, Shading -> False];
Load = ParametricPlot3D[ {x, y, z2}, {th, 0, Pi}, {v, 0, 1}, 
      Shading -> False];  Show[shell1, Load];
Clear[th, v, x, y, x1, y1, z1, z2] ;
r = 1;  x = r  Cos[th] /Cos[Pi/4 - th/2]^2/2  ; z1 = 
  r Sin[th]/ Cos[Pi/4 - th/2]^2/2  ; y = L v ; z2 = z1 + q*v*(1 - v);
shell2 = ParametricPlot3D[ {x, y, z1}, {th, 0, Pi}, {v, 0, 1}, 
    Shading -> False];  Show[shell2, Load];
