In 1933, NATCO changed their official company name from The National Fireproofing Corporation to The NATCO Corporation. Although NATCO manufactured the same products as The National Fireproofing Corporation, there were subtle changes when the company made the transition. The conduits were always called NATCO Conduits, but before the change they said “Manufactured by The National Fireproofing Corporation” after the change it became “Manufactured by The NATCO Corporation”. Since this change occurred in 1933, this information can be used to roughly date NATCO’s products.
