When the lens board arrived, the shutter doesn't quite fit and probably needs another couple of millimeters just to slide on. Thinking it might be a bad board, I checked and another #1 shuttered lens fits fine.
I haven't found any specs on a shutter size that is larger than a #1 by only a couple of milimeters. So two basic questions--what size is this? and is it a standard I can buy or am I going to have to spend an hour with a file slowly enlarging this hole?
