*This Catalog does not have a date on the catalog, but there was a 1925 price list with the catalog. I have found that USUALLY if there is a price list with a catalog, then they are usually the same date. The price lists are loose, that is, not attached to the catalog, so it is always possible that this is not a 1925 catalog.
See the price list for the Pittsburgh Branch Assembly Plant No. 33, May 12, 1925 that came with this catalog.
Note: Pages 14 and 15 appear to be missing. It appears that the book was printed that way. Must have been a misprint.
