wanted second hand awning.

I purchased a abbey 416 gts vougue 1995 last thursday, it was advertised with a isabela awning, on my 1st camping experience we found there was an awning but it was in poor condition full of mould and some of the poles where broken, now i wasnt detered but there also was no pegs very disapointed, as this is my starter caravan i didnt want to go and spend to much on a brand new awning, i would be gratefull if some one had a second hand one, or some advice on where to look and what size i would need, as i have tried to do the research but it seems there loads of different sizes and specifications and different sellers tell me different things many thanks,
