To get a good look at some fine Griffin & Howe rifles I like to go to Mike Schwandt's website: Welcome To The Schwandt Classic Arms Home Page
Look under "Bolt Rifles" (obviously).
I'm not making an endorsement, and it's not a link to a current sale. He presently doesn't have a G&H Rifle available. But in his "Sold" archives you can see nice photos of a good many he has had over the years. It's a great archive.
