Thank you Stan;
At least one person here was able to interpret what I was saying. Perhaps the reason the side lever lost out to the top lever was so many makers insisted on putting it on the wrong side.

Keep in mind everyone, this lever only withdraws the bolts. It does not require great effort to accomplish that. "Uncle Dan" Lefever's first "Hammerless" design was a sidecocker. This gun used a long lever on the left side for cocking the hammers, but it did not open the gun. It had a thumb push opener on the top tang for that. Have seen a couple of these but never had the privilege of handling one so can make no comment on their ease of use.

That left side opening lever is though extremely easy to use. Only wish the gun I have with this lever was usable. Unfortunately it went through many years of neglect & abuse before I acquired it.
