What year was my Remington 1100 made?

Is there an easy way to tell the year of manufacturer on these guns? Or at least get close? The surreal number starts with L2395

As I understand it, you can't date a modern Remington by serial number. If the barrel is original to the gun, however, there is a letter code stamped near the breech end (I think on the left side) that tells you what year the barrel was made. It's usually a single letter, but could be a double.

Weird, I know.

Take a look here and here.

I looked at that chart but I don't know if my gun was made before or after 1972 so I can't really make heads or tails of it. The number on my gun is 60 th so I guess I will keep on wondering. Thanks for the chart though.
