Petpa, welcome to JOT ! Your brochure looks like mid to late 1920's to me. Often there is a code on the back cover, in the lower right or lower left corner, that contains the date.

Thanks for your response.  Unfortunately I only have the cover of this catalog, so there are no other clues available to help determine its date.

The truck pictured, with the radiator type and flat bumper, would be a model 52, which was about 1926-1928.
