How old is this Blackjack Calssic Blades #1-7

[jclem06]

Im new to the knife world and just picked up this Black Jack Classic Blades #1-7. From the markings and my research it looks to be an early Effingham, IL made knife. Below are some pics, I hope they show. Can I get some expert opinion on this knife please. Thanks

I can't see the pic' either.

I just got my first 1-7 (and a 5 to go with it) with saber style micarta handles, and they're incredible! They are wonderfully balanced, and feel very light and fast in my hand.
