I have seen one of these cranks with just blank holes, but do not know about the assembly. Perhaps the fastenings are supposed to be inserted before ass’y, and if they are hex. Hd fastenings, perhaps nuts could be used behind the boss. If a lock tab plate is used between pairs of bolts, that still can be done, with a heavy duty spring washer behind the nut, as well as an appropriate nut threadlock solution. However, if the fastenings are supposed to be inserted before ass’y, they may have round heads with a flat on one side to prevent turning when being tightened. This type of fastening is used on a number of Austin tail shaft connections.
Hopefully, someone in the Counties Organisation will answer your question with the correct information.
Hope this assists in some way.
