I found this a while back and jumped on it. I have never seen another one. I am interested in getting pictures of a WWII grease gun suppressor if anyone has one to post. I am particularly intersted in the barrel porting. Thanks.
Here are a couple of pictures. The barrel is a Guidelamp barrel. It is also stamped F.S.CO. A 3 digit S/N was stamped near the Guidelamp name as well as on the exterior of the tube. I obtained a copy of the amnesty paperwork and the paperwork states "1949" as year acquired.
