Hello again experts.
Thank you for the input so far. I do already know all about the history of the Bath Wheel-Chair. It was actually invented in 1750 and had completely replaced the Sedan Chair in the city as early as 1830. That is one of the reasons why I think the photo could date to about 1850-1860. Which is when these Bath Chairs gained the most popularity in the city. Much of the City of Bath is on a hill and so many people, not just invalids, used the Chairs as a taxi service to get around the city. (see attached newspaper articles).
Also, and most importantly to my argument is that in the 1851 Bath Census (see attached census page) my SNOOK ancestor was actually recorded working as one of these Chairmen, he had died by 1869. His nephew then also worked as a wheel-chairman in the 1861 Bath Census (see attached census), but had become a gas-fitter by 1869. No other ancestors worked in this profession at any other time in our history, hence why I thought it must be a photo of these individuals in 1850s or 1860s.
What would you really say the date is taking all of these factors into account?
Regards, Paul.
