If anyone doesn’t want theirs anymore I’d gladly take it off your hands, thanks.
I have one in my shed that I no longer use. It has the original 3.0si back box with the innards removed and two sections of straight through pipe inside. If you can pick it up, it is yours for £100. Let me know if you are interested and I will get some pictures for you so you can see the condition of it to see if it is what you are looking for? I am based in Peterborough.
