I disassembled my 1901 Model 27 for cleaning. Somehow, I lost the thread guard that goes with the faceplate. I believe the Faceplate is part #8210 and the thread guard itself is #2827 (with #8505????). I'm getting the part numbers from a Price List of Parts for the model 27. The faceplate is fine, just need to get the thread guard. Do you have one of those?
