this is one of the most visually satisfying books i have ever seen. I have a 1922 edition vol.2 and was looking for vol.1. the book tells you, and shows you in hundreds of intricate line drawings how to make any kind of architectural features out of sheet metal. want to build an onion dome copper roof with 6 dormer windows and a cupola above it with intricate guttering etc. it shows how. the cover of my edition is green cloth with the logo of intertwined shear and soldering irons in gold leaf.copper
