Apologies again for not getting these parts and prices up weeks ago, its just been too far down the list of things to do, so tonight I've sat down and beaten it out; oh the joy of copying and pasting a word document into excel, and then converting the text in numeric format in order to convert from EUR to GBP.  Oh well, its done now.  Rather than refer to the parts by their Italian description (as they were sent to me), or refer to in their English equivalent, I've opted to refer to simply to the numbered references on the parts diagram provided.  Hopefully this makes it easier for those of you who don't speak Italian or English.  I do apologise about the resolution of the parts diagram which seems to become more difficult to read as the numbers become larger.  If you haven't found them already the Bacchi parts page is here
