If the model 24 Remington is an automatic it was made from 1922 to 1935. From overall production figures, I'd guess yours came out about the end of 1926 Actually that serial number was made in the later half of 1927, you can look up the date code for the exact month/date on the Remington Society of America's Collectors site http://remingtonsociety.com/rsa/questions/barrelcodes
