Polycarbonate conservatory roof panel (Fareham PO15)

This is a long shot but no harm in asking..... One panel of my conservatory roof has been damaged and needs replacing. It is 16mm thick, bronze on the outside, opal on the inside. This was a popular colour combination 25 years ago but is no longer made. Might there be someone who is dismantling or upgrading an old conservatory and is throwing out a panel of this colour? Or if anyone can suggest a contact where I might find one that would be a help. Thanks in advance.
