This is my example of the Prototype Optical Service Respirator 8.
My one differs from Danny's example by having a more updated speech module that is a little bit closer to the design you see on the S10.
Unfortunately the nose cup inside the mask completely crumpled up and fell out of the mask, other than that the mask is in great condition!
Me, Danny and the Bovington Tank Museum are the only known holders of SR8s (Though if I remember correctly BTM's example went missing during a rearrangement or something?)
