Anyone ever encountered interference from the plastic inserts for the spacebar in the Model F barrel plate, that interferes with the C key and the Comma key? Meaning, when you depress the key, before the key bottoms out, the bottom edge of the keys hit the top of those inserts?
I am re-assembling my 4704 107, and encountering this. I'm about to grab the original key set to look at those two keys, see if they appear any different.
Before I break out a file or dremel to relieve a little off the bottom of the keys - figured I would ask if others have seen this.
