“Sifo toys were designed to help children build their bodies by simple exercise, their minds through solving simple problems and providing necessary recreation, their motor and mechanical skills through trial and error, repetition and use of memory. They advertised that their wood was cut and sawed in their Norway, Michigan plant which was then sent to St. Paul to be finished. Sifo produced several different pull toys. The good news is that they are always marked with the Sifo name. We have included only a fraction of their toys for reference.” — antiquetoycollections.info

The Sifo Company (which did business as Sifo's Toys and The Sifo Novelty Company) was a maker of children's toys located in St. Paul, MN that was in business from 1944 until 1975. Their niche was early educational toys catalogs of the period emphasized the various properties of their toys that would entertain and educate children. Their toys were largely made of wood, with the wood milled and rendered into parts at a facility in Norway, MI and final assembly and finishing taking place at the St. Paul headquarters and factory located at 353 Rosabel Street (now Wall Street). The Saint Paul factory was razed and is now a parking lot. Sifo's best known products were the Timmy Time Clock Children's game and the Kinder City city play set. They also made "Bill Ding" stacking clowns whose physical design, but not characterization, can be seen in the Schylling company's "Wood Stacking Robots". — Wikipedia.org
