Where's the Rest?

What's left of someone's 'pride and joy' washed up with the flotsam on Cramond Beach. Registered in Norwich, but plate done by Sandy Blow Motorcycles in Perth area. There has been a lot of Motorbike thieving at the moment too so sadly it could also be the result of that.

A nice walk along the beach after the thunderstorm, but light didn't improve, went for things that could contrast well, stones, shells and small ball-bearing coals, polished glass etc, with something like a numberplate that just stands out!
