Good luck... I've searched everywhere and I can't find anything. Your best bet is to wait for a used one to pop up on ebay. You could be on the lookout for a left-handed Aldebaran Mg7. That's the Japanese version of the Core 51 Mg7. It's the exact same reel, just a different paint job. Every now and then one will pop up on ebay. Hope this helps and good luck with your search. I know how hard it is to find quality left-handed reels...
