HANDLE AND OPERATOR FOR MY CASEMENT WINDOW(S)

I HAVE BEEN TRYING FOR TWO MONTHS NOW TO RECEIVE A NEW HANDLE AND OPERATOR FOR MY CASEMENT WINDOW(S)

BELOW ARE TWO PICTURES, OLD AND NEW HANDLES AND OPERATORS.

I JUST RECEIVED YET ANOTHER NEW HANDLE AND OPERATOR FROM WINDOW PARTS.COM

THE HANDLE DOES NOT FIT OPERATOR.

THERE WERE NO MARKINGS OR NUMBERS ON THE NEW HANDLE OR OPERATOR.

I DO HAVE A U.S. PAT NO FOR THE OLD SET: 6,247,270 AND "GO". THESE NUMBERS WERE BOTH ON THE OPERATOR.

I WOULD LOVE ANY HELP YOU COULD GIVE.
