   I would recommend that you take it to a professional and have them clean 
it.  Taking apart a camera is asking for trouble unless you have the tools 
and the experience.  It is not just as simple as taking the top off the 
camera and cleaning the penta-prism.
   While you are at it, have the foam that seals the camera checked.  Our 
oldest OM-1 just had the light seals replaced because the foam was 
disintegrating.
   The 1-13 screen is an improvement over the 1-1 screen.  It has a split 
centre and a micro-prism collar.  However, its centre goes dark at about 
f5.6.  I prefer the 1-13 to the 1-1 as it is possible to sharp focus across 
the central prism on the Moon or a planet or by gently moving a star across 
the line of the prism.
   If you have can change your 1-2 order, then you are laughing.  Get a 1-8 
and then if you still have some money, the 1-12 and you should be all set.
   Clear skies!
