How to Retract a Lead Pipe

I think that this is a very, very smart mechanism to have it. The ball action retracts the lead pipe and then there's a space to then actuate the double step. And again, like, I don't think that was easy to make. That's a very complicated thing to get right. So yeah, I will be looking forward to this. This is probably something I will pick up afterwards if I'm interested in it.
