Dewey Vicknair's side leverhttps://shootingsportsman.com/vicknairoriginal/
The sidelever was chosen, because I think it is the best-looking method of operating the bolts. Invariably, the first question asked when someone sees the gun is why I made the sidelever left-handed. The answer is that I didn’t. I’m right-handed, and when holding the gun, my right thumb is on the left side, hence the lever’s location. It’s not traditionally done that way, but it works well for me; so functionality trumps tradition here. Personally, I never have understood any of the rationales behind putting the lever on the right side of a right-handed gun. Too many things in the trade are done simply because “that’s the way it’s always been done,” and the traditional position of the sidelever seems to fall into that category.
