This pic reminds me of those ancient Chinese warrior statues that were buried under ground, except they are wing nut waxes.
Here is a pic of a wing nut wax and a finished plated part. I hate modern wing nuts, they are squared off and CHEAP looking. I used to buy reproduction wing nuts that kind of look correct, but they were made out of pot metal and the threads stripped out after you tightened them up a couple of times.
Here are some late 41/42 saddlebag badge waxes. These are so nice!!
