I have not seen an Alley like it but I have certainly not seen them all. And after I looked at my Ravenswoods, I am not so sure that it's Ravenswood either, and it worries me a bit that these seem to be showing up all of a sudden - quite a few colors for Alley or Ravenswood IMO. Could it be one of Sammy's?
I wouldn't mind seeing a couple of more pics of yours.
Here are some Sammy's (Rich Shelby's pic).
