A river hunt sounds like a good outing this time of year. So at least you cooled off and found a few things, that makes for a nice day. Congrats on your hunt !!
Cool plate. Its from a Dollar watch. I love how the oil sludge protected everything. I went to sacramento last week for work. I went for a swim in the hotel pool (I never swim but it was so bleeding HOT) I dove in and cracked the crystal on my watch. When I was done swimming I looked down at the time and saw holy Fogging mess going on inside the watch EEEEK! It is a Rolex so big time panic and Im out of town. I overbite fedexd it to my watch guy in Newport. He had it less than 48 hours after the tragedy. He sent me a picture and the watch was so rusty inside I could not even read the engravings on the movement. I should have went for a swim in oil!
