   No, different every time.

   The armature isn't moving completely freely.

   I've noticed that the armature locking wedge is just rubbing the locking lever
("Armature Locking Wedge Adjustment", p. 15)
("http://www.bitsavers.org/pdf/teletype/138_Model15_Adj_Oct41.pdf"),
and I don't think that's right.  The book says .008 to .012 clearance
when the clutch is locked.

   That's a difficult adjustment.  You need an tiny .001 feeler gauge that
can turn corners.
