Attaching Older Style 150 horns (BD-Design)

I have very early Oris 150 horns I purchased from someone in Chicago who was acting as some sort of U.S. distributor before Welborne Labs. The mounting rings attach to the horns via small brass studs that line up with shallow holes drilled in a matching pattern in outside surface horns for a precarious press fit. Well, my horns no longer want to stay attached to mounting rings and come crashing down, causing all sorts of problems and damage. Is there some sort of adhesive I could use to more permanently attach the mounting rings to the horn? How are newer versions of the Oris horns attached to the mounting rings?
