Scored these beauties hunting in the Mtns around old mining claims. The button looking item is actually off a meat saw or logging saw. Most likely brass. The nozzle was used after they pressure washed the Mtn to clean the cracks and crevices in the rocks that were exposed.
Very interesting finds. I found a similar piece that came from an old saw hunting old tailings piles in Idaho a few years ago. Took me quite a while to figure out what it was.
