Weaver once made "left hand" scopes that had the windage turret on the left side. I wish they still did, as that makes the most sense for a right-handed gun.
this is an interesting comment--i had not ever heard this mentioned before.
if this is so, it isn't too surprising that weaver went and did it in years past, as they were really on top of things by "leading the way" in the initial days when telescopic sights were in their infancy...
