Mouchot Solar addendum

Augustin Mouchot
(April 2, 1825 - October 4, 1912)

I recently got a picture from a friend of a scale model of Augustin Mouchot's "Solar Boiler" It gives a much better idea of what the original might have looked like. I have no information as to what is the scale of this model, nor am I aware of where it is situated or if it is on public view. I have reproduced the photo below.
