Here are some more of a 216 I have here. For the life of me I can not find ANYTHING that makes it different from a 215 other than the ink stampings and that the 215 lacks the embossed Pentastar and the 46237 in each blade tip. Unfortunately I do not know what this came off of. I media blasted it but taped over and saved the ink stamping, the hub did have the "Engine Side" stamping.
