Yes just that photo gave a wrong patina, it's real. The one today however... I only used 1 gallon but with the cost of fuel, it's a losing game. 2 of my dependable spots were beats, or else I break even. The chain says 925 Italy on both clasps, but I think it is a fake stamp.
Same. Didn't know it the first time. Look for them ever since. They're mostly jewelry. Nothing extremely fancy or expensive.
Are you talking about the pocket knife? Or mention the post #. I have found a number of knives. There is a post in here with most of them. Found at least 2 since that photo and I found one in Colorado I sold at a yard sale
The knife, it looks like a Buck 112. Nice knives, I own a few. Some are worth $$ , but I'm not expert enough to ID them.
