I hope I'm not breaking any forum rules (I'm sure you moderators will chastise me if I am) but several years ago I was given a pristine copy of the Handbook on the steam engine by Haeder & Powles which was published well over 100 years ago but at the time really was THE book on state-of-the-art design/construction and techincal aspects of steam engines and boilers when steam was king. This book is now out of Copyright and I have now made it available by using a high quality scanner and transfering these images to CD. This book is a must for any designer/builder or enthusiast. If you are interested in purchasing a copy (at cost to me) either PM keep a look out on EBAY.
Cheers Paul
