The Dearborn Plow MPC lists the "Long Blade" jointer as p/n 103098 and used on, like Scott said, Prior Models as well as the Economy Model plow coulters. The one thing I've noticed is that I have only seen them on single bottom plows. I consider the 10-14 Two-Way Plow basically a single bottom but since they have their own jointer arm/check chain attachment they don't use jointers. I found two 5 gallon buckets of NOS jointers and palms at a friends defunct dealership years ago and he basically let me have them for nothing.
