Thanks for all of your advice. Many also wrote personally. I tend to
think that there is enough brass mass to discipate the energy of the
molten silver...but also respect the almost 300 yrs this object has
survived...and wouldn't want ot harm it. I will start by getting
waxes made and then trying my own version with a similar size of
brass and carving it. I'll report back when I have results.
Thanks for your insight!
