This is a photo posted by DPSTX in the Benchrest and Target Shooting forum. I asked questions there, but he made 2 posts and vanished.

Why does the one barrel look like it is only blued part way?

Is the Winchester stock custom made?

The rifle in the back may have a "bloop tube" on it and that being the reason it isn't blued. Does the bore go all the way to the end? Stocks are definately custom.
