Apparently, a MG maker from Arizona got the idea that he could buy MAC -10's, cut the manufacturer's name and SN off the gun, then weld it into a new made 1919, and voila, you have a registered 1919. Now the feds have filed fraud charges on him, and a number of MG dealers from Maryland, see here:http://www.subguns.com/boards/mgmsg.cgi?read=734182http://www.citypaper.com/news/story.asp?id=20486
Apparently the ATF is collecting the guns, even some that have transferred several years ago, as their interpetation is that the new guns are post -86 dealer samples, not transferable, and that the transferable guns have been destroyed by the process of cutting them apart. They are not taking them if you are a dealer, as you can have a post - 86 sample if you are one, it just destroyed the value of the gun.
I hope no-one here is caught up in this? There are a lot more guns than just 1919's involved. Word is that there's a number of different higher value transferables involved, including even a MAG 58. Don't know if any MG42's or 34's are in this yet.
