What is the mfg date of Remington model 11 serial no 1516295 no barrel code found?

Well then it must be before 1921, I think they made around just about 1,700 of them early on and then didn't continue until like 1934 or so, this is at the end of the early batch but I have no records for early non 12 gauge model 11's. Sorry that's the best I can do.
