I had Mr. Ken Ziegenbein of Little Rock, AR go and take some photos of this signal at the end of the Amtrak Siding in front of Little Rock Union Station. I knew that I had seen a photo of a D head signal in dwarf form. I remembered where and then remembered that it appears in a lot of Ken's photos from the station.

Well, per my request last night he went down to the station today and shot photos of it and got measurements of the base for me. They are posted here and look good. Special Thanks to Ken for the photos, they aided in my research a whole lot! Zach G. is going to have a base for me fabricated, he's also a big help in my entry into this hobby.
