Toilet Float Ball

[wooo stash]

I'm Just curious~I am replacing a older toilet at my Uncles house and in the tank it has the giant float ball~looks like its made out of either copper or brass. I'm just wondering if any toilet manufactures still use this system or has it been put to rest forever in favor of the tower float ?

They do, but now the float ball is either plastic or styrofoam.
