returning to the crown -
here is another example as worn by a Cinelli model B dated 1954 -
Silca frame pump in image of interest as well. It exhibits the rubber plug in the handle that the older Imperos had. This can be removed with fingers so that spare spokes can be stored inside the hollow shaft.
Business end of pump also of interest as it shows the old Silca cast metal presta head -

spanner twisting tip -
in the early images posted when headset was in place it appears headset design has an adjustable race which requires a horizontal pin tool to hold/turn. since locknut was shown loose in the photos the tool would not have been required for removal but will be needed for reassembly and adjustment. there are lots of inexpensive tools available for this application from Park, VAR and other manufactuers.
