Thanks to PhysDoc for posting the pictures. When I bought the rifle it was represented to be a Shelhamer/Neidner. When I went to Petrov's Volume 2 to find some characteristics to satisfy myself that it was indeed a Shelhamer/Neidner I found a picture of this exact rifle on page 31. The serial number is not given in the text but the knot on the left side of the the stock near the buttplate and the the brown streak on the right side of the stock prove it is the same rifle.
