Edison phonograph cylinders

I wish I didn't feel like I had to say this again, but a couple of recent
queriers would benefit by looking at AATA, most easily the 15-year
Cumulative Index, and, in addition, a glance at the archived distList.

I have never handled one of these, but I would suggest revisiting
the several responses from a few months ago on the question of stuff
that looks like mold on wax.  What was observed may of course
actually be mold, but treating it like mold if it is something else
could be a major waste of time and effort if not conservation
disaster.  There were, I recall, several references cited to
articles about wax deterioration.
