Brent, I like pre-war varmint rifles, so I'd like to stick with that theme. It is also a rather light weight barrel, so it would be a walking around varmint rifles, so no need for a 400 yard cartridge.
Michael, neither the barrel nor the stock are marked anywhere. The barrel has sort of a purplish color to the bluing. Not like any Niedner blue job I have ever seen. There is also an extra hole in the bottom of the barrel for a forend attachment that is no longer used. Makes me think that maybe someone else did the barrel work and sent it to Niedner just for the stock. I have no doubt that it is a Shelhamer stock, the checkering, styling, forend treatment, sling swivels, even has the little brass insert in the bottom of the forend for the screw head that you see in all his stocks.
Where would a guy find an original Niedner barrel?
One of Dehass' books has an action very similar to this, but I do not recall the makers name and I do not have the book handy right now.
