You all have taught me to study the photos closely. Our digital scans allow us to greatly magnify the shadows and better understand the details. Mike McKenzie was kind enough to share a slew of photos of D&RGW OC at the CRRM. All the D&RGW flangers were rebuilt with steel frames and bolsters. Sloan illustrates (courtesy of Eric Bracher, I believe) all the D&RGW flanger blade configurations. Each flanger was assigned to a different location, and the blades must have been modified based on train crew experience. OC has one of the most simple blade shapes.

This image shows the front and rear of OC's blade, and the various rivet/ bolt locations. OC seems to have a single blade, two braces--forward and rear--and some reinforcing along the bottom of the blade. The orange dots above the knife are where the blade is attached to the moving frame (you could call it a guillotine) and the yellow dots are where the two blades are bolted together. Most all of these are rivets that are filed flush with the face of the blade on OC.
