Parts Identification, please

Good evening folks

I have a few parts in my collection that I have been unable to identify over the years and hoped that the forum may be able to assist. Thanks in advance.

Rudder: has the following stamps on it “CI TE 27” “WP B0Z” and “114 DH” (in a circle)

Writing Container: made of fibre board, stamped “41550” “87639” and “62”

Fuel Cover: front – AFT FUEL 52 GALLONS DTD 230 reverse – “BF24312” “2116” “P85” (in a circle)

Door catch: “CG52A2525” “75” (in a circle)

Trim? Back Plate: no visible markings!

Airscrew: stamped “G1” on the side lamination “A.I.D. 28K” (in a square) some unidentified letters/numbers round the front rim (just visible in the picture – may in fact say “MONO” in part) all bolts stamped “764/2” some bolts stamped “AW62” (in an oval) and finally, when it was eventually cut up and the centre hole enlarged and shaped it now appears to fit an Air Ministry Mk IIIa clock

Regards
