I’ve been through both of Mr. Speed’s books. It seems that the 9mm was the largest standard bore size for the Type M. I don’t think the existence of a special ordered example is beyond the realm of possibility. Has anyone ever seen or heard of a factory made Oberndorf Mauser Type M in 9.3x 62? Except for the banner steel buttplate (I’m still looking for one), I’ve gathered all of the parts necessary to build a reasonably authentic looking Oberndorf Type M style stutzen rifle. I’d love to see picks of a real one, if such exists!
