I have been looking into the history of the Great Exhibition of 1851, the crystal palace and the exhibits there. I had a look through the list of exhibitors and found William Wheatstone (Charles brother?) exhibiting concertinas at the exhibition, which would make sense as much of the worlds latest tech was on display there, Especially as the concertina was relatively new at the time.
Here is a link to the exhibition catalogue describing the exhibit and which concertinas were on show:

Has anyone ever looked into this, perhaps there may even be photos somewhere? Daguerreotypes? If anyone knows I would love to see
