Hi Lynn,
Yes, I was totally happy when I saw what was under the buttplate.
I never dreamed that I would own anything with "Niedner" on it, or stocked by Shelhamer. This was a very wonderful surprise.
Alright, I took some more pictures for Michael and Bill.
Here is the number and initials on the bottom of the barrel.
Here is a view of the muzzle, the barrel is 32 inches long and
is 1 inch diameter at the muzzle.
Bill (xausa), you are right, it is a single-shot, here is a picture of the magazine block
and another looking down into the open action
and finally a picture of the bottom of the rifle, I think there may have been a barrel band on the rifle, but that at some later point they decided to free float it.
