After the advice I got the other day from a guy at Waterloo I decided to take a detour to Charring Cross station on my way home from work, it proved to be a bit late to get anything from them but contrary to what they said at Waterloo there are no Solari displays stored at the station to his knowledge, he gave me the card of the Duty Station Manager who I have emailed but he will be away until the end of this project, but for my own personal interest I wanted to get in contact with him so I am currently waiting for his reply.
