I bought it in person from a Bernina dealer so it's not a counterfeit, but now that I compare my foot to the pictures on the website it's clearly different. The ring for the needle is directly in line with the cone hole rather than coming off the side under the screw, and the top is not the right shape which is why I couldn't get it on my machine. A little metal part that normally slots into the back of the feet was getting in the way because this foot does not have a slot. I was able to get it hooked onto my machine by unscrewing and removing that part, but clearly it's not the right size. If I tried to use it the needle would crash into the front of the foot. According to the Bernina catalogue there is only one version of 72, but this is not the foot in the catalogue.
