It's too bad you didn't put up this post two weeks ago. A friend of mine had a pristine C&S Prophet, identical to the one in the picture, which he sold for $50, simply because he had blown a flute for so long that he couldn't figure out how to run a short reed call .... and didn't want to practice at it because he didn't want to annoy his wife, daughters and neighbors with the calling.
As originally set up, the hedge C&S Prophet is very easy to run and sounds pretty decent for a hunting call. It's a deeper sounding call, but can be tuned fairly easy to deliver higher pitched notes. However, the C&S guts are not a good choice for someone who pushes a lot of air through a call. But, goose call guts are cheap and easy to install. As my air capacity improved, I put in GK Edge E3 and E4 guts and now am using KOD guts in the two Prophets I have.
