bill,, don't really know the total situation, but it is always
better to drill a nice tight hole into the horn, and stick a
rod(attached to the silver) in with all possible surfaces, glued,,,

glued surface) rather than the rod itself,, but i really don't know
what it looks like,, best to make the rod from twisted wire, or very
roughed up,, 1st choice 12 hr epoxy,2nd 1hr,3rd 5min.
