Hi I have a 1933 Remington Noiseless Portable Typewriter.  I am looking down from the top of the typewriter and the semi-circle bar with notches in it right below the hammer arms is worn on the far right and the far left.  I believe this is causing my typewriter to skip spaces after hitting the 'a' and other keys located on the left side. 

1. Does this make any sense?

2. Is there a way to get something to replace this part? Or is there a way to put something on top of it to prevent the extra spaces I'm getting.

By the way, I know that if I type carefully I can avoid this problem, but why not fix it?
