I added a ribbon re-inker to the right side of my 28ASR. I does not interfere with ribbon eyelets or ribbon reversing mechanism in any way, and is attached with a longer 4-40 screw, replacing an existing 4-40 screw that secures the ribbon reversing lever. John, (W9DDD), reports that his 28KSR/RO has more clearance than the ASR, so it should work there as well. The details are attached below.
