As most people are right handed and usually have more power in the right arm, I would have thought that most people would wind the reel handle with their left hand??
So why is there so much choice of right hand wind reels??
It seems daft to me. Probably originated in the land of the daft, USA??
Answer to your question is yes, shakespeare do make RH wind multipliers, loads of them and no left hand wind that I know of.
As Budding Surfcaster says ABUs use numbers ending in 01 for LHW and 00 for RHW
