Looking for a window casement replacement as seen in the attached photos... This base of this part is 4 inches at its longest... and 3 and a quarter inches at its narrowest (away from the window). It has a width of 1.5 inches.

Start by looking at our 39-020 and 39-021. Could these match your old hardware?
