The 1A Autographic Special does not have a pressure plate, but everything I have taken with it has come out very sharp. I just make sure to only advance the film just when I'm ready to shoot. My only problem with the camera has been light leaks coming in from the back, I have been taping up the back with black gaffers tape and I think I have the leak problem solved. I also had Flutot's Camera Repair cla the shutter.
I believe I did just buy basic straight anchors. I then took an exacto knife to two plastic pieces and trim off the same length a little at a time, put one on each end of a 120 spool until they fit in the camera. Pretty much just trial and error.
