First of all, I just happened to have my .30-06 MR-7 with me that day, and when I pulled it out of my car and held it up and asked him "do you know what this is", he looked it over and labled it everything from a Remington, to a Winchester, to a Mauser. When I showed him the Logo on the rear of the Recoil Pad, he said it was a Remington. When I told him it was a Marlin, he asked if it was one from the 1950's. I said "no, it is not a model 55, this one is from the 1990's".
So, even though he did sound like he could have info about the .308 M/E, I thought it would be best to ask here, since he really didn't appear to know all that much about Marlins after talking to him.
He did have a Marlin from somewhere around 1936 with him. It was a beauty too.
