Looks to possibly be a set trigger, with a straight pull plunger for the 'firing' trigger - perhaps a selonoid?

Nice wood!

That's what a 'polite' person says when they don't like the looks, design or whatever of a rifle. There must be 'somthing' you can compliment - if not, invent something - HA!.
I still think that top one would be really neat in a semi-auto - auto collection of brass .17AH for gophers.

Was at the range yesterday shooting the .25/06 and .17AH. Had to wait for the barrel of the .25 to cool after every 3 shot group. With the .17 AH, I fired 40 round without stopping and the barrel never reached room temp - was still cool, yet the temp was 3 or 4 degrees above freezing.

Yeah - a .17AHBullpup semiauto would be 'super' for gophers.
