The line has been around since at least the early 90s, in fact this in was the original line that the "caramel " name was given to. The original WC founder provend very difficult to breed and it took many years to get the project going. in those years the other type of caramels started popping up in africa and very quickly became established. This original line was first owned by Ernie Wagner and the name "caramel" was first coined for it in about 1995.

I know the guy that breeds them , but he is a bit of a recluse and may not want his name mentioned.
GHI reptiles has one from this line pictured on their website if anyone wants to see it.
