Just a small spot of silicon to stop the tubes from displacing from their very shallow locations. It's easy to wipe off but holds them nicely. The original tubing was kept in with something like bostik - which was much harder to remove. However, someone in the past had used something much harder - it wasn't PVA and was almost impossible to remove. Several elbow sections were lost as they couldn't be removed from the old red tubing. Four wasp nests were removed during the exercise.

My 2nd fav thing in life after steam

If you go to Tasmania you have to visit Pearn's Steam World if you have a passion for history especially tractors and the like!
