A lot of factors in trying to age your trap. Mostly related to exposure.
Wild guess is it is nineteen seventies vintage and been down a couple decades.
Nokta FoRs Gold, a Gold Cube, 2 Keene Sluices and Lord only knows how many pans....not to mention a load of other gear my wife still doesn't know about!
Based in the "swingset" style chain (single twisted wire forms two loops) I'd go with no older than 1910 or so. And since it ends in a stake loop instead of a swivel maybe no more recent that 1960 . . . ish.
There are other makes that look VERY similar. i.e. Newhouse (predates Victor). Is there a punch-out "V" or stamped writing on the trip plate?
I agree with all that has been said.
Clean the Bait/strike plate and see if you can see a maker.
You may be able to narrow down a date a bit.
Cool find
