No front F or pearl keys on that horn, and it is definitely a Wonder series Conn stencil. There are thousands of these floating about with a wide variety of names stenciled on them. I have the same horn under the names: E. Domage, Wurlitzer, Masterbuilt. Worth having at least one model, but since they are neither rare, or have keywork up to the later New Wonder I and II models, I wouldn't pay more than $150.00 to $250.00 for one in need of a re-pad and adjustment, and I do my own sax repairs/re-pads. Rarely are they worth paying for a re-pad, save for the playing and enjoyment of the horn.
