SO163 with new emulsion now being shipped

[Bob Grassucci]

Dear all,
	It seems that Kodak has switched over to the new emulsion of SO163.  The 
way to tell the difference between the old and the new is by looking at the 
emulsion number which is an 8 digit number, for example  213 054 03.  The 
first three digits are the key.  If the number is 205 or greater you have 
the new emulsion.  Our preliminary studies showed a decrease sensitivity 
(10%) but I need to look into this more critically.  I have also heard 
reports of an increase in the fog level.  Please let me know if anyone has 
any further details.
	Bob
