cos biasi keep me wainting (via parts centre) two weeks for a plated heat exchanger
I could have sent you one next day or you could have got it direct from Claire II at 01902 304400 although they do add a carriage charge.
Bits for Ravens are a little more difficult. I think you officially have to go to the shop to the right of their factory and get them there. Its also owned by Louis but its something like a freestanding alternative to B&Q so its not seen as competition.
Any problems with Sime, ask for Terry Cawfield who should be able to sort you out.
I dont have much faith in HRPC. I once ordered a fan for an obscure Sonya Duval storage combi. They kept me waiting for about two MONTHS and then suddenly had it there! THE LABEL SHOWED THAT IT HAD BEEN DELIVERED TO THEIR BRANCH WITHIN SEVEN DAYS OF MY ORDER !!!
