Slim chance anyone will have B & S Universal Protractor head blades to fit a model # 495 Protractor head, but I want to make sure I can't buy one or both before buying stock to make a set. Blades are 6" & 12" long, and each end is not square, but angled at 45 degrees.
Like I said, not likely anyone has just blades, but still worth asking.
Also, B&S blades has a groove that runs it's length and is dead center of the blade just like a blade for a tri square.
