I came across this knife and was wondering if anybody could attest to its authenticity. It looks to be a Blackjack Model #5, but from what I have seen in the mild research online I've done the makers mark does not match 100% and the guard is gold rather than silver found in the models I have seen. The measurements of the knife are accurate, so I'm thinking right now that this knife is simply an older model. Not sure though. Can anybody tell me whether it is a true Blackjack Model #5? Any information would be most appreciated. Thank you
