Taking shape indeed and a lovely shape she is too.
I attach links to two videos for your perusal Paul
Both concern Flight Deck Operations on British Carriers and although many years removed from HMS Illustrious' era there is some great footage showing Tractors and Cranes.
The first is aboard HMS Hermes in the 1960s illustrating the different equipment types for Hangar a/c handling (powered dollies) and Flight Deck handling (Tractors)
It can be found here -

That is here -

What might be useful is seeing the state of the paintwork showing both weathering and wear and tear
Enjoy!
