original  8 page brochure of the Solem Machine Company of Rockford Illinois for the model 370 and 430 2 and 3 drum endless bed sanders they made.  Not dated possibly is c. 1920's. The company was founded in 1919. In  good condition, the large 2 page illustration has damage to the picture just below the upper hole punches. It is hole punched on the side for insertion in a binder. Please note the ingterior pages are bright white like the covers. My camera  made them look darker than they actually are.  It measures 8" x10&3/4"". Will ship in large envelope.
