    I think this mold may have been for pewter instead of silver. Think
    bullet molds. Considering its age and value I would not want to risk
    molten silver. Also there is not enough mass there for the heat to
    go somewhere. Is it a two part mold? I would do a wax cast then cast
    the wax to get a metal master and make a new rubber mold. You will
    have some shrinkage from the original but no chance of damaging it. 

    I have had brass molds for casting plaster ornaments for
    architectural work. Several of the books in my library show molds
    for tea pot handles and spout parts from that time period. Those
    molds were in cast iron. Something to think about.
