Oh-oh

This was found at the end of the driveway today.
"Sheared bolt and bracket combo", I think I'll call it.

Not entirely sure what car it's off of, or even whether it's from one of ours.
Doesn't look Panzer-like, or particularly structural. More like an exhaust support or somesuch I reckon.

Had a look under them all tonight in the rain with a torch, none of them appear to be obviously missing anything, so it'll have to wait till the weekend when daylight/jacks are more available.
