T series counterweighted cranks

[Turboterrifik]

Dear All,
I am interested in information that may exist regarding the specs of T series cranks
Specifically;
Does the 70mm 2T crank in any form come with the full set of 8 counterweights?
Are there any other types apart from the 3T-GTE crank?
Is there a company established in manufacturing these items apart from Toyota?
What balance tolerance is the crank subjected to from the factory

OK, maybe a better question to ask intially is, how many counterweights on a T series standard crank?

T and 2T is four.
3T is eight.

factory balance tolerance? no idea. for what little it costs you'd want to balance a crank before using it in a build anyway.
