Awning annexe

Hi, here's hoping some one in the group may be able to help us, we have a Dorema Vitesse porch awning and find we need a tall annexe to add on, Dorema have stopped making them now and we need help to try track one down, new or used it doesn't matter, it needs to be the maroon colour.

so if you or anyone you know has one to sell please post on here. Thanks.
