“Urban Remains: antique American architectural artifacts” is a web site featuring antique that are rare and unusual. I see that today there is an item featuring an electrical product display case of Harvey Hubbells switches and other items. It is beautiful and worth looking at.  http://www.urbanremainschicago.com/index.php/c-1930-s-remarkably-rare-and-original-harvey-hubbell-electrical-product-display-case.html
