Ogle, that is one I have never seen before, normally the patent dates are on the barrel. The trigger guard is the only metal behind the loading gate. I am curious what is the brass looking thing below the serial. I would like to see pictures of the whole gun, receiver and all if you wouldn't mind. Here is what number 127 looks like, it has a buttplate that has horizontal lines in it and says "Remington" on top and "Arms Co" on the bottom. Does your bolt say model 11 or anything on it? They weren't called Model 11's until UMC bought out Remington in 1911 and before that they were just called Remington Autoloading Shotguns, they had 6 different grades of them as well.
If you were interested in selling it I might be interested in buying it.
