Very interesting, thanks!

Some of these have much more text associated with them than others (e.g. https://collection.sciencemuseumgroup.org.uk/objects/co87277...) and it's a shame to think that people have gone to the effort of photographing them and writing them up and nobody has seen them (yet).

I guess that this URL will stop returning results eventually. I hope nobody is antisocial enough to write a script to request all the items.
