Yes- W&R is correct for the sidelock - my typo there. That'll teach me to try and write and eat sushi at the same time!

Note there were two gunmakers both called Rodgers involved in the patent.

Also correct that not all screw grip guns have intercepting sears but the better ones sold by Army & Navy and William Evans did.

Good job someone is paying attention!
