I don't recall all of the details, especially the sequence, but I had a very similar issue with my IIIc/f years ago.
I think I may have bumped the R lever late in a roll and it seemed to lose tension and caused an offset in the speed dial just like yours.
IIRC, I shot the rest of the roll and it cleared itself upon releasing of the spool.
Jeff, that is the kind of answer I was hoping for. ;-)
Thanks!!
