Noble Arms - Gallatin

The effect "You can only control 1 'Noble Arms - Gallatin' face-up on your field" is an effect that does not create a Chain Link. (If you already control a face-up "Noble Arms - Gallatin," you cannot activate a second "Noble Arms - Gallatin.")

The effect "②: The equipped monster gains 1000 ATK, and loses 200 ATK during each of your Standby Phases" is an effect that does not start a Chain Link. (This effect is applied to the equipped monster. The process of the ATK decreasing during the Standby Phase also does not start a Chain Link.)

The ATK change caused by the effect "②: The equipped monster gains 1000 ATK, and loses 200 ATK during each of your Standby Phases" is an effect that is only applied while "Noble Arms - Gallatin" is equipped to a monster.

The effect "(3): If this face-up card on the field is destroyed and sent to the GY, you can target 1 Warrior "Noble Knight" monster you control; equip this card to that Warrior "Noble Knight" monster" is an effect that activates in the GY and creates a Chain Link. (It is an effect that targets 1 Warrior-Type "Noble Knight" monster you control in your Monster Zone. It can also be activated during the Damage Step.)
