Amphibious Tank Escape Apparatus (A.T.E.A.)
The hose and mouthpiece assembly, complete with original instruction tag
Original instruction tag attached to the hose, detailing the importance of filling the canister with Protosorb (Soda Lime) prior to use.
Shut Off Valve and mouthpiece featuring Siebe Gorman manufacturer markings. This valve would only be opened when the set is required for use.
Mouthpiece and buckle assembly, identical to that on the D.S.E.A. (Davis Submarine Escape Apparatus).
Top of the canister, showing the schrader valve used for charging the set with breathing air prior to use.
Base of the canister, which interestingly utilises the eyepiece retaining ring belonging to a conventional respirator of the era with the glass replaced by a mesh screen allowing for the canister to be filled with Protosorb (Siebe Gorman branded Soda Lime).
Threaded cap on the rebreather bag, possibly for the attachment of an additional air bottle to extend use or to aid in deflation of the bag.
The original packing box for the A.T.E.A. This example has been marked in pencil as being deficient of Protosorb which has then been scribbled out, as well as a few rudimentary drawings of the A.T.E.A. set itself.
The straps are fully adjustable using heavy duty brass buckles. The set also doubled up as an emergency life preserver using the buoyancy provided by the rebreather bag.
An original and unopened tin of "Protosorb", Siebe Gorman branded soda lime intended for use with the A.T.E.A. Each set would be issued with a single tin.
