Rutland Water Cycle Route I Am Looking For Information About A Fly Rod I Have Bought Second-hand ?

I am looking for information about a fly rod I have bought second-hand ? - rutland water cycle route

The stem is 2 pieces 10 "6" rows 7-8-9 Alaska Magnamite IM8 made by Bob Church. I wonder how old it might be said, if the rod is commercially available and at what price? Also crucial for anyone using one of these bars and it is good? It would also, as I will be especially suitable Rutland Water fishing rod for deep-trawling? Thanks
