The other thing is that I have my doubts about whether we can expect recordings of all remaining Raphael symphonies at all, at least in case of those which weren't published (and this holds for any of them but the Sinfonia breve) I guess this will be difficult since I read that Raphael actually forbade the publication of any of his pieces which weren't printed during his lifetime, so it seems that most of his unnumbered symphonies are in manuscript only and might stay so forever.
Thanks for that valuable, if depressing, piece of information, Holger. That's a real shame, as I really enjoyed his second through fifth symphonies!
