Yep, it's the BreathTakers Claudia that I found. The set from Mooge has her in the boots AND in the same room as the BreathTakers pics I posted that were from a set called "Flexicon", I think. The orignal Claudia/Klaudia doesn't have the chin dimple that this girl does.
Another mystery solved.
Would be nice if andr3a shows up to find the results.
