When I think fake sidelock, I think of the guns that have the side plates just screwed to the action sides as a place to place engraving.

In the spectrum of sidelocks, there are some that only have one pin, and there are some that have 9 pins, and everything in between.

I think we are safe calling Tobins hybrids mostly because the mainspring isnt attached to the sideplate like traditional sidelocks.

Out there doing it best I can.
