Victorian Shotguns and Dogs Photo Quiz

No question No. 2 is a Lifter and is a later model with the 1 piece lifter I believe. The two types had a different shape and thickness. I also would bet it is a 10 gauge from the looks. No.4 I would put my best guess as being a top lever hammer gun. Time based on that could be set with a definite earliest possible date at the transition from 3 piece to 1 piece lifters.

I believe the first gun is a side lever of some sort as already guessed. The enlarged pictures helped.

Somebody should be able to take a guess as to grade from the checkering in the enlargement of No.4.
