For sale is a vintage manual from Josam Manufacturing Company of Michigan City, Indiana. Josam made plumbing drainage products. This 196-page book is a handy reference. It contains specifications and roughing dimensions. It is copyright 1954. It measures 5 1/4 by 6 3/4 inches and is in very good condition. See my listings for other items. I gladly combine shipping fees for multiple purchases when they can be packaged together, and I do ship internationally. Please contact me with any questions, and thanks for looking!
