Circa 1923 Norco (?) Porcelain Flush Lever

We think the stamped logo says “Norco”, it’s on the backside of this lever and it’s pretty poorly stamped into the brass. It’s 5 letters inside a diamond and Norco was a brand back then. Lever will need a square hole in the tank that’s a minimum of 5/8″ and a maximum tank thickness of 3/4″. Overall length is 10 1/4″.
