Hey KY Jon:

I'm LH and left eye dominant, and have never heard of a "central vision" stock. Have a pic of one?
Years ago I found a factory SXS Merkel with the typical raised Germanic cheekpiece, but on the right side of the stock.
Then I installed steel-safe Brileys in it, so I can use it for anything from Ruffed Grouse to geese.

I think you are correct about all the unconventional stocks built for injured vets. My dad was one of those, but luckily it was "only" his ears.
