I recently picked up a 3A in about as good of condition as possible for a 109 year old camera. The one thing I have to sort out is a ground glass, as it didn’t include one. Is there a source to find them or some dimensions available? I figured worse case scenario is I pick up a bigger one for a 4x5 and cut it to size. Also, there appears to be a missing clip to hold the ground glass down on the back side of the camera. If someone had a pic of the part I’m missing, I might be able to make something.

Thanks!
