richary: Drat. I did notice the river had broken it's banks above the weir earlier in the week during the heavy rain, but don't know if it would have gotten this high here, would be surprised. Went and had a check this afternoon but no luck. So it's either floated off somewhere or been muggled.
Decided not to replace this one as the spot isn't that special despite the history. Shame about the coins that were in there.
