I only seen those tips on new on the store/dealer shelves, they came off as soon as the saw left the store. I have yet to see anyone cutting with one still on the bar.I recall back in '78 that a friend of mine had one. I was cutting with my new Mac Timberbear and he had one of these Homies. I was rather impressed with it. However, I never quite understood why they had that nose guard on board the bar tip. Seems like it would always get in the way of large felling, bucking, noodling, etc.
