The placement of the serial number is not important except it may indicate a very early gun. Yeah, I think the metal has been refinished and the wood is either aftermarket or refinished. But like I said, I'm not an expert on this.
Right now, I think your receiver and barrel was manufactured by UMC-Remington between 1903 and 1906 is one of the two earliest examples of the Browning patent autoloader that I've ever seen.
Technically, I don't think your gun is a Model 11. I think it was built when the model was still called the Remington Autoloading Shotgun, but I repeat, I'm no expert and I could be wrong.
