If the paddles are the same as on a New Idea 270, I was able to get a full set from the local Agco dealer in 2019. In my case that was Pells out of Freemont, MI. They were very rusted but only on the surface and had never been sharpened but nothing a bench grinder couldn't fix. Also if you find they fit too tight most often you can open the gap on the tightly curled end to make it run more freely. Your of removing the rods is how I pulled min with a come-along and a tree for the last 10 years.
