Hi Stan,
Have a look at the image below. It was taken at Stratford Armouries museum in the UK (
http://www.stratfordarmouries.com/).
It is simply a piece of shaped wood, with drilled holes, allowing wire or clips to hold the swords/daggers in place. I have seen the same technique used in museums in India.
It would mean you would only need to hang (and drill) the 'shield' and not each piece individually.
Hope that helps,
Runjeet
