i think the last 2 numbers of the serial number tells the year
Go here, they lost the serial numbers. http://armscollectors.com/sn/windates.htm sorry, I meant "list" not "lost"
The Winchester model 94 30-30 was produced between 1894 and 1980. A gun dealer would be a good place to find a list of the serial numbers for all those years.
The answer appears to be 1916. Try this website for a list of Winchester Model 12 Serial numbers http://www.mchenry-sc.org/Engineering/Model_12.htm
I checked records for all Winchester "Rangers" produced. You list a serial number that would have had seven digits: "61665xx". The only seven digit serial numbers Winchester used had a first digit no higher than "2".
It is pre 1964 with a serial # of 496507
