This is a Duesenburg SJ Roadster, 1934, 1/24th scale Monogram kit. This is one of a series of classic auto kits produced in the 1970s. Although not terribly popular at the time, these kits are remarkably high quality and very detailed. They're long gone from store shelves, but can still be found from dealers, and on eBay and such.
One thing that this sort of project has in common with working on watches is that a key to a good job is treating each detail as a whole project in itself. Each individual component of the whole, no matter how small, has to be crafted as though it were itself alone the entirety of the work. There are no short cuts. With each part small treated with great care, then, one part at a time, the completed whole will succeed.
The rear end details are almost completed. There is a couple more things to add yet, and a bit of touch up here and there.
Here is the completed 1/24th scale 1934 Duesenburg SJ Roadster. There are some imperfections, but all in in all it gives a good impression I think.
