Richard, I was looking at the following site originally posted by Kat.

If you go to that site and click on the picture of the doo-dad, it will about double in size. In the white strip along side the doo-dad, small pics will apear. If you then click them, they enlarge to show various aspect of the doo-dad. I hope that's clear.

Best wishes to you.
