Hi,
I found this site while Googling for a section drawing of a Cornish mine. My interest is stationary steam engines in general & Richard Trevithick in particular. I will post my questions in a separate post.
I live in Cape Town so have no direct mining connection but have a connection to Cornish mining as my wife was a Daniell descended from 'Guinea a Minute' Daniell of Trelissick.
