SOLD FOR £94
This Silurian right arm and chest is part of the Silurian body suit sold in Bonhams Doctor Who sale in 1991. The costume had the name of the actor "Norman Comer" written in which is the name of the leader ichta. This part of the costume has the actor's name written in.
This is an amazing piece and is in its original condition, the arm has lost some reptilian latex skin.
I only know of two surviving silurians costumes from the entire history of the original dr who series - this part of the costume is from one of them.
