Looks like a long barreled Ruger single six, with wood grips. Kinda like a Colt frontier model 22 lr. It's a cowboy gun.
Its over at my dads in Sunriver, but he'll be back from Arizona on Sunday night at like 9:00 ish. If your interested, & if you still have your rangefinder by then, ill get you as many pictures as you want.
I can't even remember why he has it come to think of it... Maybe he was shootin sagerats with the grandkids. They think he's SOOO cool when he does that with a pistol, & everyone else is using thier 22 rifles. Who knows. Hahaha.
