That looks original to me. In fact, some time ago, there was a discussion about these devices on another forum that I subscribe to:

Very interesting.

I'm just a little confused here. Was a "UK machine" section not made for just this type of thread. Perhaps young Alex is not aware that there is now such a section... .

I know we are separated by a common language, but it's called a subforum.

I saw that machine at the Science Museum a few weeks ago. It's quite a large piece of kit in real life, but very clever. Just around the corner from it is a display case of gramophones and related items. I had a good look through this, much to the delight of my other half who noticed this sign among the exhibits before I did. Apologies for the poor quality camera phone image
