[Hallicrafters] Speaker Grill Cloth

[Bill Gerhold]

Anyone have a good source for speaker grill cloth?  There are many on the
web and can't decide.  Images are lousy with little description of the
pattern.  

I just picked up a very good condition R-46A speaker and the grill cloth is
a brownish (original color?) cross hatch (threads at 90 degrees to each
other).  Almost seems to be hard as metal or heavily varnished to make it
very stiff.
