Aardwolf count yourself most fortunate that your Matsumoto San hub be late eno' to have dustcaps which press fit into shell

earlier version had dust caps press fit to cones, these are more difficult to service and cone replacement tedious

earlier type is not illustrated at VB

another member of this "family" of one-piece alloy shell large flange hubs with small round holes in the flanges is the Campag Sportman

it is also a "nine holer"

its flanges have a unique height of about 57mm rather than the 63mm and 67mm (radius of spoke hole circle) sizes more commonly encountered so it is easy to spot at a distance; a flange height which places it part way between a "mid-flange" and a "large flange" -
