I paid around $8 for mine. I don't know how accurate it is for the Chessie cars, as I cannot find a picture of a 50 foot hi-cube now. I did this kit long before I was concerned with accuracy. For now, it just looks good. I would recommend this kit, just as a stand in for now. When I know more about these cars I will update this kit review.
Below is my one and only Roundhouse 50 foot hi-cube.
I just assembled it, painted the ends white, and weathered it. The
consolidated stencil should be black with white writing. It is currently
blue with white writing. A small inaccuracy that you can easily correct
with a correct decal over the one you see below. I also added the
end numbers on the white stripe, like all hi-cubes.
