Seems to me that the finish might have been blasted off for some reason as I doubt Adams ever sold any in the white to the public and if Adams did send them out in the white they might have went to a coating place around your parts of town???? Any coating places over that way? Maybe they are missing inventory as UPS cant get shipments right for nothing.
They were found by my GF in the attic space of the home she was living in.
Something tells me them things fell off the back of a truck at some time..
