Your description is too vague to be certain. A picture would help.
The average round screen color has 4-5 things on it's neck: the "Deflection Yoke" that goes somewhere between the end of the electron gun and the bell of the CRT, the "Convergence Yoke" which looks like a BIG 3 leaf clover with the CRT neck sticking through center which is normally placed over the big metal ring at the end of the electron gun (sometimes hidden but denoted with a red stripe in the CRT neck), the "Purity Rings" which look just like magnetic centering rings found on monochrome TVs, the "Blue Lateral Magnet" which was made in a few different styles that all interchange and is typically found over IIRC the second large gun element from the base, And lastly the "CRT Socket" that the CRT base pluggs into.

Some sets had a combined Purity Rings/Blue Latteral assembly and thus had only 4 things on the neck.

The convergence yoke typically has more and smaller wires than the deflection yoke that lead to a circuit board with a lot of knobs (known as the dynamic convergence board).

There are these circular ring things on the clover. I guess those are the purity magnets? I will have to take a picture of it and post it here.

The piece Im missing is the square metal piece.
