Damaged poles for a Harrison Drive Away Awning

We have been given a Harrison high-top motorhome drive away awning but some of the poles have been bent by the weight of water after a torrential downpour. Harrisons appear to have gone out of business. Has anyone a set of poles to sell for this awning or can suggest a source of finding some? (E-bay couldn't help but am continuing to look!) Alternatively, would anyone like to buy the canvas from us to replace theirs?
