I was doing research to help Florence Feldmann-Wood, who writes articles for "The Spinning Wheel Sleuth". It is a very interesting series of publications about spinning wheels. She also publishes a "Looms Supplement". She was doing an article on OH spinning wheels. It was publication #70 Oct 2010. You can order the issue from the website at http://www.spwhsl.com/iss_70/http://www.spwhsl.com/iss_70/ I hope you will get the issue.
