Winchester Model 1897 12 GA Shotgun

[crslght]

I'm tring to determine the age of a Winchester Model 1897 12 ga. shotgun. I seem to recall there was a website that you could input the serial number and it would responded with a date range of when that specific gun was manufacture. Does this ring a bell with anyone?
