i have recently discovered my late father's selectric that has been
unused for about 25 years. as an engineer i have enjoyed getting it
back in order (what a feat of IBM mechanical engineering!) and now
everything works perfectly EXCEPT the lever for switching between 10
characters/inch and 12 c/in. it moves only abit but doesn't seem to
slot into place and character spacing stays on 12 regardless of a 10 c/
in golfball inplace. i dont want to force anything. can anyone help?
ps also found boxes of unused typing 'ribbons' ,the use once type,
which are still giving top quality print - amazing.

You may already have this manual, however, here are my 2C.

The following link has some manuals for IBM Selectric/Selectric ii
Typewriters. May help you in solving your problem.
