Apparently someone in the Chicago area bought up all the
molds from ISM, but after receiving them he discovered that many were
pretty much worn out and wasn't quite sure what to do next. An employee
of Emperor's Headquarters in Chicago told me this; he also told me the
name of the purchaser but unfortunately I've forgotten both their names.
It wasn't clear if the line was to continue under the ISM label or
something else. Anyway, if you see a new microarmor line from somewhere
in Illinois, it's probably derived from ISM's old stuff.
It's too bad ISM is gone, since they made some esoteric but useful stuff
that nobody else did (especially for moderns).
