I have an e-book on compressors if anyone is interested its quite detailed for you techy guys its quite a large file (33.8mb)so dont think i can upload it to the site.
maybe you should pm wazzaaah he is the librarian around here he has a web site with a lot of Ebooks on it about metal work. it would spare you sending it to everybody who wanted it they could just go in and download it themselves
Got the link but it says 'file cannot be repaired'
Anyhoo, I've ahem....'acquired' a few compressor ebooks possibly including the same one as yours Eil, as one is about 33 Mb. I've no idea what's in them but they'll be in the same place as the others as soon as I can upload them.
