It seems like you have the old style Bilt-Best window, which was made around 1968. This operator is unfortunately no longer available. It's just too old. Looking at your photos, I suggest using something like the 39-013 operator with a 13-1/2" arm, along with a new handle like the 39-205 and a 39-533 sash track. However take note that you will need to alter your existing sill cover or make up a new one to compensate with the different shape of the new operator body. Let me know if you have any questions about my suggestion. |
