I would put on the scopes and glue them back together, one little drop at a time weeks on end.
I for one discourage anyone trying to bring back any of this type unless they are beyond saving.
The nets are hard to bring back to original life---even better is to display then as found—as you show.
I just love this stuff.
Nice finds here for sure.
Nice images--great display as well.
Marble—On!!
