You know, that actually doesn't surprise me one bit, much like I'm quite confident in that the aforementioned Cm7b9 is equally real (and a hoist of others not found within BBox). They both are, as I said before, pretty straight forward, and one has to wonder sometimes about seemingly arbitrary exclusions like that within BBox's data.
Have thanks for that link reference, though, that's one for my bookmarks for sure cool


There's only one thing to do in crisis like this - Sleep on it!
