When open again to the public, T WWM has a variety of engines pumps, and turbines, many of them actually capable of rotating under power, Gas, I C and steam. They have one of the oldest working triple expansion steam engines in the country
From what I have found, they have about the only working 9" bore Wilson oil engines, that is still left in the world.
A nice display on Stirling engines, and two full size hot air engines that run
During Covid, volunteers go in each week to turn things over and keep the exhibits free
So, well worth spending an afternoon visiting
One day, we may even meet there!
