I purchased this booklet a few years ago and have intended to scan and share since then. I finally got it scanned last night. I have sent it to Dan and it will be in the Heating Museum soon.

The booklet was published in 1911. To my surprise, our building, the Louis P. Best residence in Davenport, Iowa, Grandview Apartments since 1928, is featured in the booklet. Another house here in Rock Island, the George Wagner house, is also in the book and provides here-to-fore unknown information as to the architect.

This link should provide access to my drive.
