It's a really strange thing, there's three libraries supposed to have it on worldcat. Kent don't have it. The bl doesn't have it. Some library in the back of beyond in new zealand doesn't have it. There's a copy on amazon in Europe but it a) won't ship here and b) I don't think it exists at all.
I emailed francesco da mosto who got back to me and said it hadn't been published but hoped it would be some day. Must have been abandoned right at the last minute after cover designed and isbn assigned
