LOCATING ONE:
Many people have asked me about locating one of these lamps. Unfortunately, American Case Company, doing business in Albuquerque, NM, is no longer in business as far as I know.
However, Joann Swanson had a how-to for making a display lamp using inexpensive picture frames in Dollhouse Miniatures December 2001. They were in a center pull-out section called "Living With Miniatures."
A club in NJ made these lamps according her instructions. You can see some of them here: http://home-and-garden.webshots.com/album/54223845lmZRMa
Also, here is a source for a lamp that might work for a smaller scale setting: http://www.vandykes.com/product/02541477/
In January, 2007, I came across a company which makes display pieces for taxidermists, and lo and behold, there was a lamp! You might check them out for lamp possibilitites, plus they make all kinds of interesting display pieces useful for showcasing miniatures: http://www.woodcraftdisplay.com/Disp_case.php
This is only a display lamp base, but you can set another glass or other container on it: http://shop.vendio.com/tophat01/item/887969993/index.html
