This double cone coil was made 100 years ago.  I wasn't around then.  I
suspect it was wound expertly tight and then shellacked.  The wires are
definitely firm in place, even today.

That coil has the general appearance of Tesla's later generation conical
coils.  Do you know the dimensions and wire gauge of that conical coil?  I
may want to build that as my next Tesla coil project.
