storage unit and trolleys sell so they keep them coz they get damaged often so theres a demand for replacement bits, the coolest bit i got is the crash axe but i bet the plod wouldnt take kindly to it.

depends on the job too sometimes a company will just buy a aircraft for certain bits engines undercarriage ect, the next job down at brunters is a 737 and apparently thats having noting taken from the cabin so they could be a chance but unless you there at the time they just get scrapped too.
