Man, that's a tough one. I have a weakness and am a sucker for about all of them, British, German and domestic. When it comes to working or doing something I'm pretty decisive but when someone mentions "favorite" or "best" I'm a washtub full of indecisive goo. Of the ones I own my Johann Outschar has to be close to the top.

My little Jeffrey Rook rifle I'm working with right now is pretty decent but I don't have a picture of it. It's the typical W C Scott Rook rifle they made for about everyone and I believe mine happens to be one that was indeed finished by Jeffrey. According to Collingwood and the way mine if fitted and finished it about has to be.
