I'm surprised your search didn't turn anything up, there are quite a few images and plans on the web.
An American site, the wooden boat store has some very useful stuff, and there are many others.
You could try using the term blueprint instead of plans, and after searching click images. I've used this stuff myself for a recently finished Gar Wood speedster special, which has turned out quite nicely.
I'm also assuming you're a builder of some experience, it takes a while to make a decent model from these drawings, but it's well worth the effort.
I know you said you wanted plans, but there also some kits for similar models from Dumas,. Opinions seem to vary about them.
