I am indebted to a very frequent visitor to this blog who suggested that I try this out on my readers. The idea was to run a contest to see if people can identify what this gadget is and what use it can be put to.
Having tried it on a few knowledgeable types, I found that it will be next to impossible to identify what it is. I therefore reproduce the complete illustration and caption as a matter of interest to my readers.
If you find it difficult to read the small print, just click on the image and it will enlarge enough to be able to read the fine print.
I would still like to hold a contest. I would like my readers to hazard a guess as to who the regular visitor could have been, who suggested this idea.
