I do like your selection of drying stands
I first saw the picture and was really confused. Wha? What kind of engine...?
Then I read the text.
Looking beautiful.
It is just a beam engine.........however due to people like Savery, Newcommen Watt et al taking out long patent restrictions, the progress of steam engine design was very much delayed and other people had to come up with lots of different designs to stop litigation from the large firms.......Hence there is a rich history of sometimes bizarre and wonderfull contraptions made and quickly forgotten, So, lots of different makers produced their own prototypes. Thanks for the interest and comment.......
