Unknown Avro Lancaster parts, crash site Rhineland/Germany

Hello there!

I have several fragments from two Lancaster crash sites (both were Mk III Lancs. with Packard engines).
Would be good to know sth. about the fragements – I was not able to allocate them in my technical drawings.
The second last part is chromed but unfortunately without any marking.

Any ideas are appreciated 🙂
Thanks in advance!
Marcel
