This artefact is unquestionably a piece of a gas turbo machinery, most likely a dated aircraft engine. It is clear from the pictures that:

1. The 'silver drum' part must be composed of a corrosion resistant (likely aerospace) alloy, suggesting aircraft origin.

2. The 'silver drum' shows evidence of having been studded with blades, which have been folded over in a direction consistent, when considering the pitch of the blade stumps relative to the cylinder axis, with the device having operated as a multi-staged axial compressor that failed catastrophically.

3. Consistent with the identification of the 'silver drum' as the compressor in a turbine engine, it is obvious the central battered section formed the housing for the rotor bearings, and was formerly surrounded by combustion chambers (the remains of which can be seen);

4. And the large brown rotor at the far end of the artefact formed the turbine part of the engine, apparently with rotor blades missing.

The 1954 F-86 Sabre crash in the area seems, in all probability, to be the origin of the artefact. In fact, the J35 engine that powered the earlier sabres consisted 'of an eleven-stage axial-flow compressor', which exactly conforms with the number of bladed bands seen on the 'silver drum' in the pictures.
