I can recommend The Anson Engine Museum in Poynton, Cheshire.
Well worth a visit if you are nearby, handy from the Peak District.
A great display of engines of all shapes and sizes (incl. some steam and a W12 Bugatti/Audi engine display somewhere), and a great bunch of friendly knowledgeable guys.
Many running days:

Lots of examples and a good whizz round on their Youtube button, e.g.
