I figured it out, no scratch after exposing a few frames and opening the back. When the film rewinds it's making the WRONG sound and after removing the film from the canister the scratch is there. Off to the repair shop in Walnut Creek for a cleaning, I'll tell them APUG sent me.
You can't be lost if you don't care where you are.
I experienced the same problem with my Leica R8 camera last year: horizontal scratches on my film. I sent it to Leica's New Jersey plant and they replaced the pressure plate. That solved the problem and I've not seen a recurrence of scratching since then.
