Hello Nils, if you go to the following link
http://wp.scn.ru/en/ww2/f/52/9 then scroll down and on the right of the page you will see a list of spitfires. Select a serial number of an aircraft in which you may be interested. This will then bring up a series of images of Spitfires, click on this image and it will bring up an enlarged photo. Hope this may be of help.
Kind regards
Ross
