I believe the only problem is that your cab mock-up is slightly too big. Keep the boiler as-is, and reduce the size of the cab as necessary.
I have concluded that Steve is right. The cab needs to be narrower. Thanks to all for the helpful comments. I will adjust the dome and tender heights, but the boiler will remain 1 3/4", true to the drawing. Here is the "Big Cab" looking from above.
Here is a modified cab, also looking from above, made narrower with front doors open. The verticality of the open doors helps to make it "feel" less wide and in fact it is less wide.
Now we can compare a photo of the model taken at a similar angle to a
photo of the Gurley
This is good. The narrower cab will also help to expose a thin edge of diamond plate just above the red trim stripe.
Concerning cab construction, I think that I am going to use a "sandwiching" technique. I am not very good at painting trim on windows. I found that when modeling the Retlaw 1 coaches, painting the red trim in place never produced a satisfactory result. What did work was pre-painting strips of styrene red and then gluing them onto the inside. Using this idea, I will make a 3 or 4 part "sandwich" of each of the sides of the cab. These will be painted before gluing them together. Here is a little mock-up to test the best method of gluing. The biggest issue will be the appearance of the edge at openings.
