I have an Electra 120 with 1 1/2 spacing in Elite typeface.  I have an Electra 220 in Pica with 1 1/2 spacing

My Hermes 3000 has the same problem.  I never knew it had that function before now after reading this.  Now my perfect Hermes 3000 is no longer perfect.  Damn!
 

Just acquired this delightful machine from 1962, my first Olympia, and I have a few questions.  The ribbon reversal mechanism:  Does it require rivets in the ribbon to work properly or is it just tension that reverses it?  I loaded some ribbons with rivets and it did not work that well.  There is no mention of rivets in the manual either.  On another matter I have read somewhere that the SM-7 model is just a SM-3 or 4 with a more modern outer shell.  Is that true and would a 1955 SM service manual apply to the SM-7?   BTW Duane Jenson's video on reducing the shift key pressure really helped.

I have a Montgomery Ward Signature 513(JP-3) that I am attempting to fix the escapement.  This has 3 eccentric screw settings, 2 in on the front plate and 1 in the rear that is unable to be accessed unless the whole escapement is removed.  Would love to know what sequence and settings that a manual might offer as this is one of the most frustrating tasks that I have encountered.  The carriage either runs free or is totally locked...can't find a happy medium.  All parts appear ok as there is no evidence of missing or broken parts.  I have been playing with this for weeks and am not getting anywhere.  I got this through SGW so don't know its history.  Hint:  When I received the typewriter the drawband was not attached.  So, if anyone could share the escapement chapter of the manual, that would be greatly appreciated.

I have a 1968 Classic 12 with elite font that has the 1-1.5-2 line spacing and two Galaxie 12's, both pica font with 1-2-3 spacing from 1975 and '76.  I have 5 SCM electrics from late 60's and early 70's with a mixture of the two fonts, Coronets , Sears Medalist, Electra's, that have 1-1.5-2-2.5-3 ability.
