MAHR TRADE CATALOG oil furnace core ovens forge + 1930s
This is a full-size advertising trade catalog for industrial oil-burning equipment, issued by the Mahr Manufacturing Company of Minneapolis, Minnesota. There is no publishing date, but I would guess roughly circa 1920's-1930's. It includes a 12-page catalog of Mahr Core Ovens (called "Catalog 200"), plus more than 50 different 2-sided single-sheet product advertising bulletins (or Sheets) issued by the company, each for a different products, each well-illustrated with b&w photos and full descriptions of each item, with descriptive text and data; the bulletins are all numbered in the 500's and 600's and are not in numerical order; Catalog 200 is near the middle.
Roughly 100+ total pages. Abundantly illustrated throughout with hundreds of b&w photos of products, installations, and applications, many showing workers and factory interiors. Also includes one additional laid-in page. A very uncommon catalog.
