I got a treadle a few weeeks ago and lostn51 told me it was a New Home model A made in 1882 it's in very rough shape and the poor baby needs lots of help but I only paid $15 on creigs list. I have found a manual and a few parts and a book on how to clean her up. It will be a slow process but I can hardly wait to hear her hummmmm. happy holidays Mary
