Unfortunately these kinds of threads deteriorate into two camps. Real world and common sense vs a strict interpretation of the law. How many on here actually believe that the BATF is going to descend on surviving family members with both feet when and if it comes to light that grampa’s WW2 relic had the serial number ground off in one location? To what end?? And how many who seem to get some satisfaction in trying to impose rules on others would actually use a cutting torch on a nice family heirloom if it belonged to their family?
