It appears it was a kit company's spin off (Hobby Barn/Quality Line) of the Curare. Hanno did not develop it. It is not SPA legal but cetainly would fit with BPA. Best description I found was this:

"I am positive its not the Curare. From the pics I'm pretty sure its the Super Curare from Hobby Barn (Quality Line). It was a Curare with a reshaped nose and fin."

Here is the best photo I found from one thread...
