Doug: If this old memory serves me right I believe that the last time I saw such box/wrapping was when I first started into the contender's and I think that was the mid 60's. I still have a 11 inch .223 barrel, with that old deep blue finish.
As for the Zipper, maybe the same era and into the 70's, but that is just a guess on my part.
Looks like you scored well. Bill K
