Hey Guys, I posted a thread earlier about my Moss. Mariner and I discovered something inside of the receiver. It appears that my supposedly new gun has some initials scratched into it. The letters are TSH. Does anyone know if this was done at the factory or could this possibly be someones name? Has anyone ever seen this on other Mariners or field models? My cruiser and turkey field gun do not show this mark. I also heard that the original design for these guns was from Smith and Wesson. Is this true? I love Mossbergs and have never experienced a problem with reliability. Anyone with a little more knowledge about this, please respond. Thanks
