Fred,

I hate to rain on your parade but I think a little more research might be in order. We need to learn some background on Ben Comfort and see if he used a Niedner rifle.

The crown is right on, a square crown with bright metal.

Is the caliber marked on the barrel.

In my database 1461 & 1465 the only two numbers close to your rifle are .300 H&H.

In my experience Tom Shelhamer used a stamp with his name on it as seen below.



You might also take a close look at his inletting. Did you take pictures of the barrel and action inletting?
