The S&P Check Protector, also known as the Nafew Check Perforator, was a mechanical device designed to safeguard checks against fraud during the late 19th and early 20th centuries.
Sittman & Pitt Co. was involved in the production of check protectors. These devices were designed to punch holes in checks that were specifically printed for use with these machines. Although the company’s check protectors are less well-documented, they contributed to the evolution of financial security mechanisms during that era.

While the details of their other ventures remain somewhat elusive, Sittman & Pitt’s legacy lives on as trailblazers in the world of mechanical gaming and financial technology.
