Should you ever need reference photos of the Point of Ayr engine, I took rather more than I have posted here. Also the photos on here were scans from the prints, rather than from the negatives, which would have better definition. You would be welcome, if you ever needed them.
In passing, my Dad once worked at Llay Main in the early 1930s as a compensation clerk before returning to Lancashire to take up town planning. He remained friends with the electrician there into the late 1960s.
