I acquired a SMC Sterling, #6MSE165248 recently and after researching on line, I can't see that there there is any significant differences between the Sterling and Super Sterling of this era. I have looked at the Database and at e-bay, and You Tube videos  but still have not come up with a definitive answer.   Does anyone know?  As best as I can figure out this was made in 1969 or '70.  
Note:  In my previous post about 1972 Consumer Reports ratings, they lump the Sterling and Super Sterling together with same features.

My guess is the Sears brand was made by Brother.  SCM made the Pennys brand.  Ollivetti seems to have made the Wards brand.  If someone knows otherwise feel free to correct me.  My apologies for the poor initial post as I put everything in Word...it looked great but when transferred to the forum it looks awful.

Took the plunge, and looked for any parts disengaged or stuck.  Everything looked intacked.  Pressing the red tab key seemed a little stiff so I put a 1 small drop of light oil on an area  that looked right.  For 5 min it worked and I thought my job was done.  Then I had trouble with the tab clearence and that took a lot of time.  I concluded it was due to a funky tab set lever in the front of the machine( have to play with lever to find the "sweet spot" in order for it to work).  Then I discovered the red tab key no longer worked.  I spent several more hours experimenting and observing and could not recreate my initial success.  I decided that I could go no further knowing my limitations.  At this time I will live with the original problem.   At least I was able to clean the innards better and cleaned out the foam rot from the sound damping material.  What do repairman replace this with?
 

I acquired a VG condition Olivetti that required minimal cleaning and appears to work in all aspects but was initially thinking the tab control was not operable.  I am more familiar a with SMC Classic 12 so I was stumped as to why when I set the tab that after pressing Red tab key that that the carriage never moved.  It took me over 30 minutes of playing with this that I discovered it will work if I simultaneously press Red tab key and the carriage release lever...in other words it is a two finger operation instead of one finger Red tab press.  Is this normal?  The skimpy manual, really a   printed card, two sided, does not help.  I realize that some typewriters don't have tab functions at all and I myself will use it sparingly.   Just curious.
