Info Needed: Stevens 311E SxS

[rmaxey]

New to the forum. I've been all over the web trying to gather information on this old 16-gauge 311E shotgun I purchased a few years ago. The previous owner had it in a state of disrepair so I bought it to get it functioning again. What can y'all tell me about this model?

Year of manufacture?
Choke?

Anything else of interest based on the photos?

I figured if there was one place on the web for Savage/Stevens info, this had to be it!

Since my links to the photos don't seem to be working, here's a link to view them: https://1drv.ms/f/s!AoPmudSbhSCGkcw2rllGOiH_qjXRkA
