Any Remington 1100 experts here?

[RangerClay]

I have a Remington 1100 in 16 gauge.  It was my first shotgun, a gift to me from my father in 1984.  He bought it used.

 

I'm trying to do some research on it's history but the stamps on barrel are different than the guide the Remington Society provides.  The guide says I should have two letters than a number but I have 3 letters.

 

For those who understand Remington's, the stamps on the right side are .... W E N 8

 

Does this make sense to anyone?
