Identification of aircraft parts found at Throckmorton

[sampowell05]

Can anyone help me to identify these aircraft parts?

Both items were found in RAF Pershore at Throckmorton airfield not far from Worcester.

One of the items has a serial number/batch number (G12330

With a bit of research it seems like they used the Wellington, Hurricane and Tomahawk,spitfire

A few wellingtons did crash there but not sure if they are from a wreckage.

Any help would be greatly appreciated.

Wellingtons used the Bristol Pegasus radial
I'm just wondering if your second pic is of an RAE air compressor (see diagram right-hand side, 6th label down). You can just about make out the geared drive present on the top of your artefact and the pipe union at the other end

I take it photos 1 and 3 are of part one and photos 2 and 4 are the second part. Can you please clean up part one using an ultrasonic cleaner if you have one or a brush and soapy water if not and take more photos of that looking for more part numbers and/or inspection stamps or logos. Photos of all six angles on each part will provide more detail. A clean photo of this might provide material information.

G12330 is the part number of that particular cover on that component. That identifies it as a part not designed by Bristol Aero Engines (they all start FB) so does make it an accessory if part of the powerplant as does seem quite reasonable. Unfortunately I recently lost nearly all my RAF manuals when a computer power supply failure destroyed several of my storage hard drives and their mirrors but my memory of the RAE compressor is that it is a six sided low pressure unit and the diagram C Colin1 provided confirms that shape if nothing else. That diagram also shows a BTH compressor lower down which I am not familiar with. Having two compressors on one engine is unusual, especially on a fighter engine as that illustrated version is. The BTH may be a high pressure unit but those were usually Hymatic units. BTH did make vacuum pumps and those did have four bolts though.
