Can't remember, I think it was on the site of a Scottish lampworker. An inventor without a patent is someone who has had an idea and thinks that they have never come across it before.
Reminds me when I published 'Getting Off in London', I got inundated with claims that I had stolen their idea. While researching it an old codger asked me what I was doing, he told me that he had bought and used similar booklet around the time of WW2. The venture lost so much money that I should have got the other 'inventors' to cough up
