1943 Lancaster crash debris:Can anyone identify these parts?

Assorted fragments from a Lancaster crash in Lincolnshire found in the 1990. Can anyone identify the numbered pieces?
The perspex is 8 mm thick (as opposed to 4 mm thick perspex that was also found at the site). Any idea where on the plane it might have come from?
The black items and blue fragment are made of Bakelite. There is writing on one black fragment (no. 2.) ‘NORMAL’ with a vertical arrow.
Some other pieces are shown on a separated thread.
Many thanks
K.
