Graham is very knowlegable to say the least. He belongs to the group that I learned how to clean and repair my machine from. I have since gotten away from it but he always gives great advice and from what I have seen on the group is a very nice person.He even mailed me a part for one of my machines from his home. I love his stories too. Here is the link if anyone is interested.
