Autoloader aka model 11

[Barton92]

I have a model 11 and have some questions about the year it was manufactured. I have looked at the barrel and it is stamped EWW3. If I have read it right it would be oct of 1950. There is no others stamps on the barrel that would indicate on when it was manufactured. Therefore I believe that the marking on the barrel is the date that it was repaired. Would it be possible that it is an early 1905-1911 model autoloader and not the model 11 ? I am new are trying to date Remington firearms any info will be helpful thank you
