Does anyone know the WW year codes from 2014 to present?

I probably can't help much, but I do have the older Winchester-Western lot code dating information. I have no idea if it was used in 2014 and later. I think that was around the time that Winchester moved from East Alton to Mississippi, and they may have changed their lot numbering protocols. PM me with the lot number you have and I'll see if the information I have makes sense.
