Last night I went to the back of my safe and pulled out this !937 BSW K98. It is one of my older ones that I have . On first look , I noticed a front sight cover, and laminated stock with a cupped but plate. I had never noticed these changes. The rifle is totally matching including the trigger guard screws. It was missing a front barrel band which I put one on. My question is , did the front sight get modified or am I looking at a barrel replacement? I realize that the stock is a replacement. Any markings I should be looking for? I,m sorry for no pictures , but I,m challenged with pictures. Any help would be greatly appreciated. Banjomike
