A large, alien-looking contraption, this respirator could be aptly described as a sack attached to a metal frame.The crux of the C3 respirator stems from a rubberised fabric ‘bag’ which contains the infant. This bag enveloped the child’s entire body to protect them from poisonous gases. It is important for collectors to note that this ‘bag’ is often found in a dried condition, where the rubber surface has cracked and dried into a semi-hardened state. It is placed in the vertical cabinet on the top shelf.
