Thanks to member TT18 Timbo it appears that the item in post #11 is possibly a terminal which lives in the suppressor box of a P3 engine driven generator. Where would I be without you on that one Timbo 😎

Ok how about this one from a separate crash site nearby although not entirely sure it’s Canberra, but marked TYER’S LO# No 191#22.
Any ideas?
