I have some new additions.

Left to right. And some of what I know about them.
1. Lohman
2. Olt Timberhole Duck Call #TH-96
3. Fred Bailey (LaGrange, Illinois) - (1905-deseased) It is a cedar call with "BAILEY" stamped on the barrel. Fred can be found in Christensen's book page 50 and Harlan's book page 214.
4. Bill Dowdle Duck (Memphis, TN) don't know much about him. Searching.
5. Howard Harlan "The Heavy Duty" Rosewood (Nashville, TN) finding more and more. Will give more info later.
6. Joseph "Tex" Wirtz (1914-1977) walnut (Chicago, Illinois) Beginning in the late 1940's, Tex made duck calls bearing the "Tex Wirtz" name for sale through Marble Arm's "Game Getter" line. . Most calls were walnut while deluxe versions were available in zebrawood and other exotic woods. You can see more of Tex Wirtz's calls in Christensen's book, page 170-171 and Harlan's book, page 192. This is the "odd ball" of the group. I bought the Olt, lohman, this call in a lot. It was listed as an unknown call and it is actually the one I know the most about. Really a like this call.
7. Glenn Scobey (Newbern, TN) Walnut -

Of these, for some reason I find my self most proud of this one.
Mint In the Box, Heavy Duty Call Company by Howard Harlan, rosewood.
Also, I spent to much on these, and I am in trouble. So, I'll be hanging out with them a lot for a while.
