A crafty Japanese copy or maybe, possibly, W&A? Vintage Tom Mount article by Ken Hart claims the W&A consolette was used by the Kent Drum Co. (see page 1, photo #6). There are some subtle differences but the article says there were some variations. The nuts and bolts should tell the story. MIJ is probably metric fasteners, W&A would be english. The square head nut and wrench seems MIJ to avoid copyright infringement.
Kent did use the W&A mount early on I have had them . The same ones used by Gretsch . But the one I posted above for sure is MIJ and looks just like the one in the original post .
