Finally, I got a little time to myself so that I could clean up and fit the auxhilary service valve I had been after for so long. Many thanks to Brian and Ed for their assistance in obtaining one.
As you can see from the first two pictures, Brians' description of Rocking Horse Manure is not far wrong, I dug, scraped, polished and washed tons of it out of the valve body



Cleaning up was a process of leaving to soak in water free paraffin, more expensive than the usual stuff but the parts do not go rusty over a few days, then carefully polishing internally and externally with a well used green cleaning pad stolen from the kitchen when the 'boss' wasn't looking

I know Brian advocates the careful use of Brasso but a well used, mild scouring pad (emphasis on the 'well used' part) carefully used in a circular motion is similar to what we used to use after we had honed cylinders during manufacture in a 'past life'.
Replaced a couple of 'O' rings that looked doubtful, had a pipe made up then fitted it all to Eve yesterday.
It Works ! It Works ! It Works !
Do I sound happy ?

Painting will come later, after I've attempted to repair the hedger but, here's a couple of pictures of a Major fitted with Rocking Horse Manure.
Thanks again Brian and Ed, 24 hour guard now being mounted



Mike
