A lot of the time if the LFS doesn't have a clue what it is, because its just listed "cranberry acro" on thier manifest, they will usually provide where they got it. Sometimes that can be traced back to the supplier.....say ORA for instance where you just narrowed the possibilities down, or to another store which got the same piece, but is in better/more mature condition for identification. (just trying to explain the method behind the madness so you can try next time)
I am not for sure, but Tort probably isn't a bad place to start for now. BTW, It looks like its going to turn blue from the pic.
Plugtypes can be a tell tale sometimes, which is what I was after.
