The Pipe Fitters Blue Book or The Pipe Fabricators Blue Book, by W.V. "Duffy" Graves.
Aha! More texts to hunt for my library. I do have PIPE FITTER’S AND PIPE WELDER’S HANDBOOK, THE, by FRANKLAND, THOMAS W. 1955
Also been cataloging every single text of any kind into Excel spreadsheets, under topics. Easy to sort, easier to search (Ctrl F). Once the ceiling gets sheetrock and insulation blown in, building closed bookcases for them all. Might 'number them' ala Dewey Decimal System, in same prefixes (and extended suffixes) as found in libraries.


PS......
Just added those to list in Amazon, and found this note:
BUYERS BEWARE - COUNTERFEIT COPIES OF The Pipe Fitters Blue Book are being sold on AMAZON. The ONLY authorized sellers of The Pipe Fitters Blue Book by WV Graves are; - Amazon.com - Graves Publishing Company (pipefitterbluebook) - thegangbox and - RG Sellers ALL other sellers are not authorized sellers and have a high probability of being a counterfeit copy. The counterfeit copies are poor quality replications that fall apart after minimal use and do not reflect the quality and integrity that we provide with Graves Publishing Company.

That is just one example proliferating because online selling of new items can be very convoluted and deceptive. Most if not all purchases of old texts is very safe.
