That's a lovely rifle.

I do like the snap action guns too.
I have a tiny hammerless snap action cape gun with neat little gold cocking indicators and a two position flip rear sight in .22 and 9 rimfire shotshell. It also relies on lever throw to cock the action. Got it for my daughter, I'll get to run it till she's old enough to hold it.
I have a hammergun mate to it as well.
The guys at Puglisi (sp?) have an interesting double rifle in 6x58 -I think- that has somewhat of a snap action arrangement, but the system is operated by a third trigger of sorts that runs a lever that's coaxial with the trigger guard, and swings back into the action instead of pivoting in front of it.
Cool little gun.
