FWIW, there actually is a Garret in America - Texas of all places. Some rich dude acquired one of the little South African 2-foot jobs and shipped it to his private estate. There were one or two pics of her in steam in Railpictures.net about a year or so ago. I'll see if I can track them down and post the link.
Now, here are a couple of shots with some weathering, crew, and "stuff" on the running boards. A "dirt" overspray will blend it all together but the Dullcote makes the rivets visible.
The weather is still kind of "iffy" so she hasn't touched the rails on the layout...yet. But I am getting itchy to run trains so hopefully soon the sun will come out and the rain will stay away. #4 is the "big power" and a joy to operate.
