What is the filled in hole located on the right buttstock of Finnish rifles?
In most cases this is where there was once a unit id disc. These discs were dropped on most rifles around the time of the Winter War, as rifles that were captured gave too much information to the enemy. Some disks did survive but it is not common to locate rifles that still have these in place. It is most common to see such discs in M27 rifles. One might also see such a filled hole in areas of the stock where that could not have had a stock disc. In most cases this is a Finnish repair of stock damage. The repair is very common and almost looks like dark wood putty.
