Different scissors and collars. I'll fetch the list next week. Easy common switch. Form and W/B.
Dearest, let me explain you why no one is taking you seriously. It takes just few minutes to check facts nowadays. For example, the scissors of the H model and those of the heavy duty nose gear are THE SAME PART NUMBER. The collar is different between the H model and serial numbers before 15064532. However, the standard and heavy duty nose gears of the earlier models use the same collar. So essentially, you are wrong again.
If I may ask, what is the reason you try to answer questions that you clearly don't understand or know about?
