Powdered Iron Toroids

Hi Friends,

I am building an Antenna Tuning Unit which is presented in the ARRL handbook 2006.This unit needs a coil wound on a T-130-2 powdered iron toroid.I have several toroids in my junk box,but the problem is that none of them has any identification codes.

I shall be very grateful if someone gives me the diamensions of this T-130-2 toroid (so that I can check with my junk box items & select) or points me to a site where I can extract such details.
