This is what the manufacturer states:” is a panchromatically sensitized special negative black and white film with fine grain, good resolution and contour sharpness. ”   They recommend development in THEIR chemical developer which is where my photos went off the track - have it on order now.  

Needless to say this stuff was anything but fine grained.  I haven’t seen this large of grain anywhere.  Was developed in HC110 B.  Will show the next roll shot as per their recommendations.
