Thanks everyone, found one.
I have it and not using it. Unfortunately, I’m away on business for the next 5 weeks… and no one is at my house.
I can wait… Wont need it for any races this year, nothing long distance enough to need it pressingly

How interesting. I actually made something very similar for my P2, although this one looks like it has a bit more flexibility.
