There was another "S" brand that one of our members used to frequently mention (cause he owned one of the few examples) but I can't conjure up that name right now....definitely a rare one IIRC
Perhaps you are thinking of @

Save for the circle the "S" is very similar?
Other differences and similarities will be found at the
source of the above pictures.
Random shot of through chainstay RD cable routing on a random example found

Hope this is helpful?
Good Fortune with your project!
