Hi, I'd love to be able to do it, but my hard drive crashed a few years ago. Back then, what I did was to ask a designer friend of mine to draw it and it was not something too much complicated, so perhaps ou can do it and share the result.I'm really sorry that I can't provide what you've asked.Good luck!
