H & Z All-Purpose Willys-approved Mixer Brochure
This mixer was featured in the 1949 Willys Overland Equipment Book. It was manufactured by Hertzler and Zook, a company established in 1899 out of Belleville, Pennsylvania, that manufactured an array of machinery and farm implements. There are still a few catalogs left out there, such as this 1926-27 catalog for sale at Abe Books.

Orchard Sprayers By Field Force Manufacturing
These documents were in a late 1940s Willys Overland binder.
There seems to be a very slight difference between the two sprayer packages offered by Field Force Manufacturing. One package used a pump with stainless steel non-magnetic plungers that gave the pump higher capacity and more pressure capability. It weighed slightly more, too.
All-Purpose Advertising in Late 1955
The Truck ad is from the September 8, 1955, issue of the Heppner Gazette-Times, while the wagon is from the October 27, 1955, issue. I guess the 1955 fall advertising theme was “All-Purpose”.

Using the Heath Hitch, a person could attach several different attachments. This brochure came from a late 1940s Willys-Overland Equipment Book.
1953 “I’ll take the Jeep” Ad For a CJ-3B
I’ll take the jeep, too! This early CJ-3B ad is in the May 7, 1953, issue of the Heppner Gazette Times one I hadn’t seen.
Packaged Pump Brochure
1961? Howe Commando Fire Truck Brochure on eBay
The numbers at the bottom suggest to me the date of this brochure is September, 1961. But, this still has the split glass, so those numbers might not be referring to the date.
