Rudder template for DS1

My father in-law is in the process of renovating a DS1 that he found in the back of a junk yard. He plans to give it to my son when he is done. The last thing he needs to do is build a new rudder. He is a woodworker and is not intimidated by building it from scratch. However, he cannot find plans or a template. Does anyone have any advice for how he can get hold of the original template for the rudder?
Thanks a ton!
