Sorry; I didn't catch this post earlier. I contacted some folks I know who contacted VT on my behalf and they responded that this line has been discontinued (item# provided) and there was no data available. Based on your description it was the short head spey (vs mid and long). I requested 7, 8 and 9 which were the possible line ratings for this rod although I would tend to guess that the 8 would be the one.
Since dealers need the help clearing overstock you might find these lines for a song somewhere if you are interested. If it's too light you would have a problem; but if it's too heavy you could probably cut it back and re-splice to make a sweet little Skagit or Scandinavian style head; or cut from the middle and loop for tips, etc.
IMHO, this emphasizes the value of companies like Rio posting their grain / length information on-line.
