It depends on what your objective is. If it is to collect older Max Grey and USHobbies stuff, this is not it. but if you just like nice older models, you have something unique. I think the detail is probably a little better on this than on an MG version which I have. There are more turnings such as the generator on the MG and more Lost was castings on the newer Williams.
The Williams most probably came as a 2 rail engine. They did them both ways, my B6 came new as 2 rail. You have a nicely customized model that is unique. As a model it is probably as good as the MG. As a collection piece that you want to be all original, it is not.
