Has anyone seen or used one of these

Do you already it or did you just order it? None of the pictures show Magnum bolt pattern. I am wondering if that is just another Speedmaster error in listing or is the picture wrong?

I ordered it last week with an estimated March 2 ship date. It could be a listing error, which would be a shame but not an issue for me. But if you look at the pictures it seems that the bolt holes are slotted to allow the vertical magnum bolt angle, coupled with some slant cut spacers it could work.

Either way, I’ll let everyone know when I receive it.
