Spanish Armada guns, again

I still am interested in getting more information about guns carried by the ships in the Spanish Armada. In an article from 2002, published in British Archaeology, Colin Martin says that the inventories listing the guns for almost all the ships in the Spanish Armada exists. I need to find out how to get a copy, as that would be invaluable. Colin Martin is or was at St. Andrews, so I need to find out from him about getting the gun lists.
