Hello Norman,
that's a good idea, here are some wavs:
Internet Archive: Details: bastards-partial-clock-test-A Internet Archive: Details: bastards-partial-clock-test-B
I forgot the fades on the second one but you'll get the idea. I don't know if archive.org defaults to an mp3 in their "player" on that site or to the file I uploaded, but you'll see wav as one of the download options.
