I have not posted photos to date because the family camera failed a few weeks ago and the boat builder claimed inability to take photos and transfer them to me. Today I used my phone (old Nokia 2600C) to get some (poor) photos.
#39 shows the loop in the steam leg of the water gauge. I think the consensus now is that a loop of this type will not be a problem.
#39 and #40 show the water gauge cocks meeting the requirements for the procedures listed by bhk. Note that the water leg is straight.
Well, the preview of my previous post showed two photos. Here is #40 again. Well, that doesn't work because the forum has reached its limit (a 65 kB image). I will investigate 3rd party image storage sites.
