Very sorry to hear your news, Skitch. I know that area well, we often camp at Glenridding, the other end of the lake from Pooley bridge.
There are several people here that keep an eye on Thorns coming onto the market, so you did the right thing by letting the Forum know.
Angle grinders can get through pretty well anything if villains have a bit of time and space / access . . . .
