What are the degrees of flap for a model III wing at full flap? 15?, 20?, something else?

And for those who use flaps on take off, how many degrees (approx) do you generally use for shortest take off?

What I am trying to figure out is where is 15 degrees on the flap handle? I use 1/2 flap then pull full flap to "jump" off the runway. What I don't know is what degree of flap are those settings on the model III wing?

You are coming to the factory fly in aren't you?
