I've got the Airfix 1/24 Spitfire V and wanted to do something a little more different with it than what's in the box. After looking around I decided on a P.R. IV in SEAC markings. After searching through some literature I found pictures of the aircraft I want to portray.

Can anyone tell me what work I would need to carry out to convert the standard Mk V into this PR IV? I'm assuming that things like the gunsight, armament etc were removed but I need to know how many cameras were installed and where and anything else that I'll need to add/remove to make this particular Spitfire.
Any help would be much appreciated.
Cheers, Harri.
