Well, that first offer went well; so I'll try again.
I've got three of the four 1925 (first) editions of Audels Plumbers and Steam Fitters Guides, volumes #1, #2 and #3.
Who might treasure these? They are fascinating. Volume 3 has a nice section on domestic water supply that includes wells and windmills. 20 pages of windmill diagrams and parts labelled photos and tables!
Volume 1 has an interesting section on bending lead waste pipe. Somewhere in there is a hot water radiator system mounted under cast iron streetcar seats to warm passengers. Interestingly, I was reading yesterday about the Milwaukee streetcar workers (my grandfather was one) striking to have the cars enclosed. One of their drivers had frozen in his seat and unable to avoid a fatal accident for all occupants.
I would call these near fine. They are green leatherette and the gilt edging wraps around all three sides.
AbeBooks pricing starts at $9 each. I'd like $15 for all three, plus $5 shipping.
