Unique bayonet mount on Auto Mamiya/Sekor ES lens

I'm wondering if someone can tell me more about this lens' unique bayonet mount, and if it is adaptable to an EOS camera. I've done a lot of research and have not found any definitive answers. This lens was designed for the Mamiya Auto XTL camera. It definitely doesn't fit into an m42 mount. Would it fit a k mount? What about with modifications? I've read the flange distance is 44.5 on another forum.

Any help is greatly appreciated!
