Adjusting the paper feed mechanism - part 2

A FEW PICTURES HIGHLIGHTING THE ISSUE

Looking from the front, you can see the gap between the platen and the front feed rollers even though they are at their extreme upward position.

Compare this to the rollers which touch on the front of my working 1053 below:

From the rear, no such problem appears. Below are the views of both 1053 units with the rear feed rollers touching the platen.

This was the range of motion I could achieve with the paper feed frame relative to the typewriter body. As you can see, it doesn't seem to move the front rollers up at all. 

This is quite vexing. I still don't understand what is going wrong with the 1053. Every measurement I take of the parts, their separations and placements, and the motion of the parts is the same between the machines, yet the results are not.
