I found these mounts in my spares box. Does anyone know the brand?

To me they look like Kury.

Do you know which Kuryakyn pegs you have mounted? I compared them to the Ergo II and couldn't see a way these would work. I found them on the Kuryakyn website.

I guess the part I am missing is the Magnum clamp to go around the vertical crash bar.

You are missing the clamps, they are the offset peg mounts.
I had them from another bike so I used them.
This may give you a better idea,,,
