Lego Spiderman 4851 Origins Rare Set 98% Complete

Lego Spiderman The Origins (4851 - boxed and with full instructions).  A very rare set these days, with rare figures.  It is 98% complete, with just 2 pieces missing:-

The main missing part is the perspex front of the LAB C35 capsule (would measure about 2.5" x 3") and slides into the front grooved bricks.

The second part is one of the longish side perspex windows that forms part of a glass cabinet that has 2 spiders within.  I have substituted the missing piece of perspex for a smaller perspex window attached to a 2 x 1 white block (to make up the height).  I am sure an exact replica window could still be sourced via Lego.

The box is in good condition as is the instruction booklet.  The pieces are all clean and in v. good order and the whole set comes from a clean, smoke and pet free home.  The children have outgrown lego, hence sale.
