the process of forming rusticated concrete blocks was simplified to the point that sears was able to start selling concrete block machines in their catalogs to the general public. a catalog from 1939 offered two options for buyers interested in forming their own concrete blocks. the "wizard" concrete block machine was available for $32.95 and produced 8 x 8 x 16 inch blocks in a "medium rock-face design". for $52.95, a prospective buyer could get the "triumph" concrete block machine which had the capacity of producing between 200 and 250 blocks per day.
