Thanks to all for the nice comments.
The images, as usual, have pointed out a couple of areas that need a touch up and yes the orange connector does not belong where you can see it. I will have to tuck it into the tender shell. As far as the distance between the tender and boiler shell, I don't know, but I have to keep in mind that it will run on club layout with generous curves as well as home layouts with less generous curves.
I am thinking about converting my UP 844 into UP8444 and TTG scheme with white (silver ?) stripes. Should be easier because the domes will pop out of the boiler shell and cab pops off so no masking. Just another "round to it". Perhaps I should start with a UP838.
