The manifold was found near Gardner 1, the survey benchmark that was placed by the NZ survey of 1985 just inside the inlet on the village side. It very clearly was made from stainless steel which had been cut fairly crudely by hand, and had a part number stamped into it. If memory serves, the part number started with 32-xxxxxxx, which upon research via sat phone turned out to be a B-24 part number.
It was pretty exciting for a brief period between discovery and confirmation of the part number as we were pretty sure we had an aircraft engine part, but the more we thought about the part number the more obvious it became that it was not from the Electra. Then came the confirmation that it was a B-24 part number which of course deflated all our enthusiasm.
I'll see if I can find photos of it and the part number.
