Didn't most people fish RHW back when the 1492 was first produced? Weren't very few of the early Medalists offered as a LHW reel?
I usually fish LHW but most of my vintage reels are RHW, including many Medalists, so I just fish them that way. You can convert Medalists now with the OneFoot parts but back when they were manufactured most of them were RHW.
