The plumbing for the whistle valve was progressed by constructing a tee piece out of brass bar and silver soldering that to the plumbing. The tee was turned and a hex put on the end to represent the union nut. Have later found out that the forward pipe run of live steam goes to the front of the smokebox. Couldn't tell where it went behind the smoke deflectors!
The steam supply was also done, it is a convoluted bend in the plumbing. There is a small stop valve right next to the gland but it couldn't be fitted if I was to fit the gland studs and nuts after the fact, which I did using tweezers. The gland and plumbing was silver soldered and the elbow and a forward pipe run done for the whistle supply in the smokebox.
Dummy bolts were fitted top and bottom of the cover plate and it's really held by the 4x 10BA screws either side. The whole assembly fits well, looks very complicated when it's off the smokebox, and will be able to be removed as one unit.
Happy steaming!
