The camera head also gets flushed with a low pressure Argon gas fill and is quickly plugged with the revamped desiccant cylinder. Argon is a noble gas hence won't cause any nasty corrosion problems.
Peter I will send my STL11 when it needs doing if you don't mind. What do you charge for the service?
