Bean Spray Pump Co Lansing, MI Hand and Power Sprayers Catalog No. 34 32pp (#2)

I would date this brochure to 1919–1921, with 1920 being the most likely year. Tractor references. The brochure illustrates a Case tractor pulling the Californian Disk Harrow. Case was heavily promoting its new kerosene tractor line beginning in 1919–1920, making this combination especially characteristic of that period.
