Following the fun we had with the Benthic Sampler in 'The Nature Photography Thread' earlier this evening, Stefan thought it might be a good idea to start a 'name the object' thread.

So if you own an unusual or mysterious item, that you think others might have trouble naming, post a picture in here and let us try to guess what it is...... just for fun.

I'll start the ball rolling with a relatively easy one.... it's all I could find at short notice.

"What's This?"
