Thankyou for all the responses.
I have no idea where the balls came from.
Drawings for the Stuart Victoria and Governor are on their way.
The shaft which the governor spins around on is bent, so needs replacing.
Next project is to tidy up the GLR boiler and hydraulic test it.
A ceramic gas burner ring is on it's way as well.
When I learn how to post photos before and after shots may be of interest.
Thanks again for all your support. Mike
