Wanted: Modern Cannon extended lense

Hello folks, wondering if I can source a pair or two of the 360 extended lenses for early series Cannons with the screw holding it in place.
I know I have em but cannot find where they ended up.

I may actually have one of these, which you can have for cost of shipping. Will go dig and confirm.

Is this the right thing? I think it's a V3 like this: https://strobesnmore.com/products/feniex-cannon-360-optic-kit-v3

I just don't seem to have the center screw

Thank you so much for the effort Froom.
Unfortunately, my cannons are version 2 w the disconnect plug and the extended lense and diffuser is held in place by screw,
