  1. There's a gentleman in Green Bay, Wisconsin that built a running model of the Monitors engine. https://www.google.com/search?q=uss+monitor+steam+engine+model&oq=uss+mintor+engine&aqs=chrome.3.69i57j0i13l2j0i22i30.13380j0j4&client=tablet-android-samsung&sourceid=chrome-mobile&ie=UTF-8# Monitors engine not only had to be of low overall height. It had to be narrow enough to fit into the fairly narrow hull. Also in terms of a fairly small steam engine with a good power to weight ration one needs to look at the Doble steam cars. https://www.google.com/url?sa=t&source=web&rct=j&url=https://en.wikipedia.org/wiki/Doble_steam_car&ved=2ahUKEwjFkujcxI_wAhUCWs0KHWcDD1IQFjAAegQICRAC&usg=AOvVaw2oGS36VjpaQ3domemBTQZq. Plus the concept of double acting engines is not limited to steam power https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.gasenginemagazine.com/gas-engines/1907-snow-zm0z16jjzhur&ved=2ahUKEwjqlo6Vx4_wAhXaKM0KHcocC9IQFjAFegQIBBAC&usg=AOvVaw3PLTKQTvOY7unnd_excDxF And a minature version https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.artisanideas.com/product/9780941653411/Build-the-Snow-by-Doug-Kelley-a-Tandem,-Double-Acting-Engine.html&ved=2ahUKEwjqlo6Vx4_wAhXaKM0KHcocC9IQFjAHegQICRAC&usg=AOvVaw13Qiun_DQMM-ik1_YhK8se&cshid=1619015861650
