Not to rain on your post too much, but the 3rd Rail Virginian El-2 is not a brass model. It is a plastic model with brass details. However, plastic renders detail at a higher level than brass, so I don't mind.
At the same time I do enjoy good brass models. I wish I had some more pictures of my brass. Most of it is sitting in boxes awaiting a layout that largely exists in my mind. A few that I have photographed are shown below. Not shown are several of my Williams "budget" brass steam locomotives and my collection of PRR 2 rail passenger equipment from Sunset, PSC, Alco Models, and Custom Brass. I also have not photographed my Overland P5a that make the MTH version look like a bad toy.
