I have 3 of these acute-matte (non-D) screens, they are a matte field with etched crosshairs and are very bright compared to the standard 500c screens, I think they are as bright as the D models but not sure, they certainly compare to them at a much lower price. I'm quite sure the model number is 42165 on these. They are in exc- condition, no scratches or marks other than on the frame. Great price! I will take $50.00 each shipped in the CONUS.
