No, I'm afraid it does NOT fit the 135mm f/4.7 Optar lens frequently found on a Crown Graphic. That was my mistake in misidentifying it. The adapter ring for the Optar is a 1-1/2 inch/38mm fit, not the 1-5/8 inch/41mm ring being offered here by Dan. I own both that Optar lens and the 38mm matching shade, so I know this is correct.
Still a very nice condition shade being offered, however...
