ZPI Handle Inertia

I purchased this used, so I'm unsure if it's inertia or if it's been combined with other parts. The handle is for Daiwa, and I used it with Shimano by adding a spacer. The nuts included are for Shimano (left and right) and Daiwa (left only). I don't have an opportunity to use it, so I'd like someone else to take it.
