Bill and Jill Meier had this display at YPCIC, Hemingray, The Experimental Age. The various rarities and oddotoes of engineeering interest, but never saw large production numbers. Mostly produced in the 1930s. I'll post additional close-ups.

Bill's photo is a lot better, I still have to figure out the flash settings to get the pictures properly exposed. It's fine for close-ups but it is a bit dim for a "distance" shot.
