I seek information on a 1913 Melville Clark Apollo for rebuild. I'm looking for a tubing diagram, availability of a test roll or any information on how to set up the expression system. Much of the tubing has rotted and is missing. I have attached a picture of the tracker bar and underside. Thanks, Walt Gerber [ Tracker Bar [ http://www.mmdigest.com/Attachments/16/03/18/160318_050638_Apollo%201.jpg [ Underside [ http://www.mmdigest.com/Attachments/16/03/18/160318_050638_Apollo%202.jpg [ Underside [ http://www.mmdigest.com/Attachments/16/03/18/160318_050638_Apollo%203.jpg [ Underside [ http://www.mmdigest.com/Attachments/16/03/18/160318_050638_Apollo4.jpg
